Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492666, here are decompositions:

3 + 31492663 = 31492666
89 + 31492577 = 31492666
113 + 31492553 = 31492666
137 + 31492529 = 31492666
173 + 31492493 = 31492666
263 + 31492403 = 31492666
347 + 31492319 = 31492666
389 + 31492277 = 31492666

Showing the first eight; more decompositions exist.
