Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529964, here are decompositions:

31 + 31529933 = 31529964
41 + 31529923 = 31529964
73 + 31529891 = 31529964
83 + 31529881 = 31529964
181 + 31529783 = 31529964
283 + 31529681 = 31529964
293 + 31529671 = 31529964
313 + 31529651 = 31529964

Showing the first eight; more decompositions exist.
