Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530744, here are decompositions:

31 + 31530713 = 31530744
41 + 31530703 = 31530744
43 + 31530701 = 31530744
61 + 31530683 = 31530744
83 + 31530661 = 31530744
101 + 31530643 = 31530744
103 + 31530641 = 31530744
107 + 31530637 = 31530744

Showing the first eight; more decompositions exist.
