Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529710, here are decompositions:

29 + 31529681 = 31529710
41 + 31529669 = 31529710
59 + 31529651 = 31529710
239 + 31529471 = 31529710
263 + 31529447 = 31529710
389 + 31529321 = 31529710
431 + 31529279 = 31529710
461 + 31529249 = 31529710

Showing the first eight; more decompositions exist.
