Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492984, here are decompositions:

41 + 31492943 = 31492984
137 + 31492847 = 31492984
227 + 31492757 = 31492984
233 + 31492751 = 31492984
293 + 31492691 = 31492984
317 + 31492667 = 31492984
431 + 31492553 = 31492984
443 + 31492541 = 31492984

Showing the first eight; more decompositions exist.
