Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611696, here are decompositions:

23 + 31611673 = 31611696
29 + 31611667 = 31611696
37 + 31611659 = 31611696
79 + 31611617 = 31611696
89 + 31611607 = 31611696
113 + 31611583 = 31611696
157 + 31611539 = 31611696
223 + 31611473 = 31611696

Showing the first eight; more decompositions exist.
