Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529934, here are decompositions:

11 + 31529923 = 31529934
43 + 31529891 = 31529934
53 + 31529881 = 31529934
151 + 31529783 = 31529934
257 + 31529677 = 31529934
263 + 31529671 = 31529934
283 + 31529651 = 31529934
311 + 31529623 = 31529934

Showing the first eight; more decompositions exist.
