Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529682, here are decompositions:

5 + 31529677 = 31529682
11 + 31529671 = 31529682
13 + 31529669 = 31529682
31 + 31529651 = 31529682
53 + 31529629 = 31529682
59 + 31529623 = 31529682
89 + 31529593 = 31529682
131 + 31529551 = 31529682

Showing the first eight; more decompositions exist.
