Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611246, here are decompositions:

59 + 31611187 = 31611246
83 + 31611163 = 31611246
109 + 31611137 = 31611246
157 + 31611089 = 31611246
179 + 31611067 = 31611246
197 + 31611049 = 31611246
223 + 31611023 = 31611246
229 + 31611017 = 31611246

Showing the first eight; more decompositions exist.
