Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529708, here are decompositions:

31 + 31529677 = 31529708
37 + 31529671 = 31529708
79 + 31529629 = 31529708
151 + 31529557 = 31529708
157 + 31529551 = 31529708
229 + 31529479 = 31529708
277 + 31529431 = 31529708
349 + 31529359 = 31529708

Showing the first eight; more decompositions exist.
