Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490034, here are decompositions:

11 + 31490023 = 31490034
71 + 31489963 = 31490034
151 + 31489883 = 31490034
193 + 31489841 = 31490034
281 + 31489753 = 31490034
283 + 31489751 = 31490034
311 + 31489723 = 31490034
313 + 31489721 = 31490034

Showing the first eight; more decompositions exist.
