Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492692, here are decompositions:

29 + 31492663 = 31492692
41 + 31492651 = 31492692
89 + 31492603 = 31492692
139 + 31492553 = 31492692
151 + 31492541 = 31492692
163 + 31492529 = 31492692
199 + 31492493 = 31492692
239 + 31492453 = 31492692

Showing the first eight; more decompositions exist.
