Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490014, here are decompositions:

71 + 31489943 = 31490014
113 + 31489901 = 31490014
131 + 31489883 = 31490014
173 + 31489841 = 31490014
197 + 31489817 = 31490014
263 + 31489751 = 31490014
293 + 31489721 = 31490014
401 + 31489613 = 31490014

Showing the first eight; more decompositions exist.
