Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529676, here are decompositions:

5 + 31529671 = 31529676
7 + 31529669 = 31529676
47 + 31529629 = 31529676
53 + 31529623 = 31529676
83 + 31529593 = 31529676
109 + 31529567 = 31529676
137 + 31529539 = 31529676
197 + 31529479 = 31529676

Showing the first eight; more decompositions exist.
