Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492744, here are decompositions:

47 + 31492697 = 31492744
53 + 31492691 = 31492744
167 + 31492577 = 31492744
191 + 31492553 = 31492744
251 + 31492493 = 31492744
467 + 31492277 = 31492744
587 + 31492157 = 31492744
653 + 31492091 = 31492744

Showing the first eight; more decompositions exist.
