Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492846, here are decompositions:

5 + 31492841 = 31492846
89 + 31492757 = 31492846
149 + 31492697 = 31492846
179 + 31492667 = 31492846
269 + 31492577 = 31492846
293 + 31492553 = 31492846
317 + 31492529 = 31492846
353 + 31492493 = 31492846

Showing the first eight; more decompositions exist.
