Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611944, here are decompositions:

3 + 31611941 = 31611944
37 + 31611907 = 31611944
61 + 31611883 = 31611944
103 + 31611841 = 31611944
127 + 31611817 = 31611944
211 + 31611733 = 31611944
241 + 31611703 = 31611944
271 + 31611673 = 31611944

Showing the first eight; more decompositions exist.
