Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492954, here are decompositions:

11 + 31492943 = 31492954
47 + 31492907 = 31492954
107 + 31492847 = 31492954
113 + 31492841 = 31492954
173 + 31492781 = 31492954
197 + 31492757 = 31492954
257 + 31492697 = 31492954
263 + 31492691 = 31492954

Showing the first eight; more decompositions exist.
