Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529086, here are decompositions:

5 + 31529081 = 31529086
89 + 31528997 = 31529086
233 + 31528853 = 31529086
263 + 31528823 = 31529086
389 + 31528697 = 31529086
587 + 31528499 = 31529086
653 + 31528433 = 31529086
773 + 31528313 = 31529086

Showing the first eight; more decompositions exist.
