Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529296, here are decompositions:

17 + 31529279 = 31529296
23 + 31529273 = 31529296
47 + 31529249 = 31529296
53 + 31529243 = 31529296
83 + 31529213 = 31529296
443 + 31528853 = 31529296
599 + 31528697 = 31529296
683 + 31528613 = 31529296

Showing the first eight; more decompositions exist.
