Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492582, here are decompositions:

5 + 31492577 = 31492582
29 + 31492553 = 31492582
41 + 31492541 = 31492582
53 + 31492529 = 31492582
89 + 31492493 = 31492582
179 + 31492403 = 31492582
263 + 31492319 = 31492582
419 + 31492163 = 31492582

Showing the first eight; more decompositions exist.
