Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613656, here are decompositions:

17 + 31613639 = 31613656
29 + 31613627 = 31613656
257 + 31613399 = 31613656
743 + 31612913 = 31613656
929 + 31612727 = 31613656
1109 + 31612547 = 31613656
1433 + 31612223 = 31613656
1613 + 31612043 = 31613656

Showing the first eight; more decompositions exist.
