The letters of TALES have been added to the grid to form six words, one being a lingual import into English.

L	E	A	S	T
S	L	A	T	E
S	T	A	L	E
S	T	E	A	L
T	A	E	L	S
T	A	L	E	S

Assign a base 10 digit to each of the letters in the grid to create an alphametic so that each row but one forms a 5-digit prime number.

This situation can occur in three ways, and logic should prevail.

(In reply to computer solution by Charlie)

I know it is usually assumed that leading zeroes are excluded, yet, if permitted, the following is a tenth solution:

LEAST : 03917 [prime]
SLATE : 10973 [prime]
STALE : 17903 [prime] 
STEAL : 17390 [composite]
TALES : 79031 [prime]
TAELS : 79301 [prime]

I am curious as to maximum number of primes for the anagrams of TALES that exist that would include the additonal anagrams of TALES: LEATS, SALET, SETAL, STELA, TEALS, TESLA.

LEATS: 03971 [composite]
SALET: 19037 [prime]
SETAL: 13790 [composite]
STELA: 17309 [composite]
TEALS: 73901 [composite]
TESLA: 73109 [composite]

Total primes for anagrams with {0,1,3,7,9) = 6. 

(You are welcome to post a solution to the unasked question, Charlie, but if it is of no interst to you, no matter. Thank you, anyway.)
