Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529914, here are decompositions:

23 + 31529891 = 31529914
71 + 31529843 = 31529914
131 + 31529783 = 31529914
197 + 31529717 = 31529914
233 + 31529681 = 31529914
263 + 31529651 = 31529914
347 + 31529567 = 31529914
443 + 31529471 = 31529914

Showing the first eight; more decompositions exist.
