Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529962, here are decompositions:

29 + 31529933 = 31529962
71 + 31529891 = 31529962
179 + 31529783 = 31529962
281 + 31529681 = 31529962
293 + 31529669 = 31529962
311 + 31529651 = 31529962
491 + 31529471 = 31529962
641 + 31529321 = 31529962

Showing the first eight; more decompositions exist.
