Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611274, here are decompositions:

3 + 31611271 = 31611274
137 + 31611137 = 31611274
173 + 31611101 = 31611274
251 + 31611023 = 31611274
257 + 31611017 = 31611274
263 + 31611011 = 31611274
503 + 31610771 = 31611274
701 + 31610573 = 31611274

Showing the first eight; more decompositions exist.
