Find Counterexamples (Posted on 2016-07-06) Difficulty: 3 of 5
There was once a conjecture that every odd number except 1 could be written as the sum of a power of 2 and a prime.

Examples:
3=20+2
99=25+67

Find the counterexamples less than 1000.

Show there are an infinite number of counterexamples.
