Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611150, here are decompositions:

13 + 31611137 = 31611150
23 + 31611127 = 31611150
37 + 31611113 = 31611150
61 + 31611089 = 31611150
83 + 31611067 = 31611150
101 + 31611049 = 31611150
107 + 31611043 = 31611150
113 + 31611037 = 31611150

Showing the first eight; more decompositions exist.
