Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611514, here are decompositions:

5 + 31611509 = 31611514
41 + 31611473 = 31611514
47 + 31611467 = 31611514
173 + 31611341 = 31611514
191 + 31611323 = 31611514
401 + 31611113 = 31611514
491 + 31611023 = 31611514
503 + 31611011 = 31611514

Showing the first eight; more decompositions exist.
