Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529844, here are decompositions:

61 + 31529783 = 31529844
127 + 31529717 = 31529844
163 + 31529681 = 31529844
167 + 31529677 = 31529844
173 + 31529671 = 31529844
193 + 31529651 = 31529844
251 + 31529593 = 31529844
277 + 31529567 = 31529844

Showing the first eight; more decompositions exist.
