Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529912, here are decompositions:

13 + 31529899 = 31529912
31 + 31529881 = 31529912
163 + 31529749 = 31529912
241 + 31529671 = 31529912
283 + 31529629 = 31529912
373 + 31529539 = 31529912
433 + 31529479 = 31529912
499 + 31529413 = 31529912

Showing the first eight; more decompositions exist.
