Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529832, here are decompositions:

13 + 31529819 = 31529832
83 + 31529749 = 31529832
151 + 31529681 = 31529832
163 + 31529669 = 31529832
181 + 31529651 = 31529832
239 + 31529593 = 31529832
281 + 31529551 = 31529832
293 + 31529539 = 31529832

Showing the first eight; more decompositions exist.
