Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529884, here are decompositions:

3 + 31529881 = 31529884
41 + 31529843 = 31529884
101 + 31529783 = 31529884
167 + 31529717 = 31529884
233 + 31529651 = 31529884
317 + 31529567 = 31529884
563 + 31529321 = 31529884
641 + 31529243 = 31529884

Showing the first eight; more decompositions exist.
