Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529804, here are decompositions:

127 + 31529677 = 31529804
181 + 31529623 = 31529804
211 + 31529593 = 31529804
283 + 31529521 = 31529804
373 + 31529431 = 31529804
457 + 31529347 = 31529804
547 + 31529257 = 31529804
751 + 31529053 = 31529804

Showing the first eight; more decompositions exist.
