Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496746, here are decompositions:

5 + 31496741 = 31496746
53 + 31496693 = 31496746
173 + 31496573 = 31496746
179 + 31496567 = 31496746
227 + 31496519 = 31496746
257 + 31496489 = 31496746
317 + 31496429 = 31496746
647 + 31496099 = 31496746

Showing the first eight; more decompositions exist.
