Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611198, here are decompositions:

11 + 31611187 = 31611198
61 + 31611137 = 31611198
71 + 31611127 = 31611198
97 + 31611101 = 31611198
109 + 31611089 = 31611198
131 + 31611067 = 31611198
149 + 31611049 = 31611198
181 + 31611017 = 31611198

Showing the first eight; more decompositions exist.
