Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559682, here are decompositions:

5 + 31559677 = 31559682
23 + 31559659 = 31559682
29 + 31559653 = 31559682
31 + 31559651 = 31559682
41 + 31559641 = 31559682
43 + 31559639 = 31559682
59 + 31559623 = 31559682
109 + 31559573 = 31559682

Showing the first eight; more decompositions exist.
