Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611732, here are decompositions:

13 + 31611719 = 31611732
23 + 31611709 = 31611732
29 + 31611703 = 31611732
59 + 31611673 = 31611732
73 + 31611659 = 31611732
149 + 31611583 = 31611732
151 + 31611581 = 31611732
179 + 31611553 = 31611732

Showing the first eight; more decompositions exist.
