Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529294, here are decompositions:

37 + 31529257 = 31529294
127 + 31529167 = 31529294
241 + 31529053 = 31529294
463 + 31528831 = 31529294
487 + 31528807 = 31529294
571 + 31528723 = 31529294
661 + 31528633 = 31529294
673 + 31528621 = 31529294

Showing the first eight; more decompositions exist.
