Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492792, here are decompositions:

11 + 31492781 = 31492792
41 + 31492751 = 31492792
101 + 31492691 = 31492792
239 + 31492553 = 31492792
251 + 31492541 = 31492792
263 + 31492529 = 31492792
389 + 31492403 = 31492792
701 + 31492091 = 31492792

Showing the first eight; more decompositions exist.
