Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540744, here are decompositions:

17 + 31540727 = 31540744
101 + 31540643 = 31540744
107 + 31540637 = 31540744
113 + 31540631 = 31540744
251 + 31540493 = 31540744
401 + 31540343 = 31540744
503 + 31540241 = 31540744
563 + 31540181 = 31540744

Showing the first eight; more decompositions exist.
