The equation below involves four 5-digits prime numbers:

A + B + C = D

A, B and C are consecutives, B and D are palindromes.

Find A, B, C and D.

I'm with Vernon on this.  I don't have the sophisticated tools, i.e. mathematical know-how, to solve this problem analytically.  I wouldn't know where to begin.  I could however easily solve it by computer.

I would certainly regret it if no one posted an analytical solution to this problem, because I would miss the opportunity to learn.
