Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611276, here are decompositions:

5 + 31611271 = 31611276
89 + 31611187 = 31611276
113 + 31611163 = 31611276
139 + 31611137 = 31611276
149 + 31611127 = 31611276
163 + 31611113 = 31611276
227 + 31611049 = 31611276
233 + 31611043 = 31611276

Showing the first eight; more decompositions exist.
