Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492732, here are decompositions:

41 + 31492691 = 31492732
179 + 31492553 = 31492732
191 + 31492541 = 31492732
239 + 31492493 = 31492732
311 + 31492421 = 31492732
569 + 31492163 = 31492732
641 + 31492091 = 31492732
653 + 31492079 = 31492732

Showing the first eight; more decompositions exist.
