Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530648, here are decompositions:

5 + 31530643 = 31530648
7 + 31530641 = 31530648
11 + 31530637 = 31530648
31 + 31530617 = 31530648
41 + 31530607 = 31530648
59 + 31530589 = 31530648
151 + 31530497 = 31530648
197 + 31530451 = 31530648

Showing the first eight; more decompositions exist.
