Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613652, here are decompositions:

13 + 31613639 = 31613652
23 + 31613629 = 31613652
29 + 31613623 = 31613652
71 + 31613581 = 31613652
73 + 31613579 = 31613652
101 + 31613551 = 31613652
113 + 31613539 = 31613652
139 + 31613513 = 31613652

Showing the first eight; more decompositions exist.
