Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529634, here are decompositions:

5 + 31529629 = 31529634
11 + 31529623 = 31529634
41 + 31529593 = 31529634
67 + 31529567 = 31529634
83 + 31529551 = 31529634
113 + 31529521 = 31529634
127 + 31529507 = 31529634
163 + 31529471 = 31529634

Showing the first eight; more decompositions exist.
