Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518262, here are decompositions:

3 + 31518259 = 31518262
23 + 31518239 = 31518262
53 + 31518209 = 31518262
89 + 31518173 = 31518262
173 + 31518089 = 31518262
239 + 31518023 = 31518262
263 + 31517999 = 31518262
311 + 31517951 = 31518262

Showing the first eight; more decompositions exist.
