Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613646, here are decompositions:

7 + 31613639 = 31613646
17 + 31613629 = 31613646
19 + 31613627 = 31613646
23 + 31613623 = 31613646
67 + 31613579 = 31613646
107 + 31613539 = 31613646
263 + 31613383 = 31613646
269 + 31613377 = 31613646

Showing the first eight; more decompositions exist.
