Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611726, here are decompositions:

7 + 31611719 = 31611726
17 + 31611709 = 31611726
23 + 31611703 = 31611726
53 + 31611673 = 31611726
59 + 31611667 = 31611726
67 + 31611659 = 31611726
79 + 31611647 = 31611726
109 + 31611617 = 31611726

Showing the first eight; more decompositions exist.
