Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529656, here are decompositions:

5 + 31529651 = 31529656
89 + 31529567 = 31529656
149 + 31529507 = 31529656
383 + 31529273 = 31529656
443 + 31529213 = 31529656
569 + 31529087 = 31529656
659 + 31528997 = 31529656
1097 + 31528559 = 31529656

Showing the first eight; more decompositions exist.
