Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492714, here are decompositions:

17 + 31492697 = 31492714
23 + 31492691 = 31492714
47 + 31492667 = 31492714
137 + 31492577 = 31492714
173 + 31492541 = 31492714
293 + 31492421 = 31492714
311 + 31492403 = 31492714
557 + 31492157 = 31492714

Showing the first eight; more decompositions exist.
