Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492064, here are decompositions:

3 + 31492061 = 31492064
13 + 31492051 = 31492064
31 + 31492033 = 31492064
151 + 31491913 = 31492064
223 + 31491841 = 31492064
271 + 31491793 = 31492064
277 + 31491787 = 31492064
337 + 31491727 = 31492064

Showing the first eight; more decompositions exist.
