Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529714, here are decompositions:

37 + 31529677 = 31529714
43 + 31529671 = 31529714
157 + 31529557 = 31529714
163 + 31529551 = 31529714
193 + 31529521 = 31529714
283 + 31529431 = 31529714
367 + 31529347 = 31529714
457 + 31529257 = 31529714

Showing the first eight; more decompositions exist.
