Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611836, here are decompositions:

7 + 31611829 = 31611836
19 + 31611817 = 31611836
79 + 31611757 = 31611836
103 + 31611733 = 31611836
127 + 31611709 = 31611836
163 + 31611673 = 31611836
229 + 31611607 = 31611836
283 + 31611553 = 31611836

Showing the first eight; more decompositions exist.
