Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530674, here are decompositions:

13 + 31530661 = 31530674
31 + 31530643 = 31530674
37 + 31530637 = 31530674
67 + 31530607 = 31530674
103 + 31530571 = 31530674
151 + 31530523 = 31530674
223 + 31530451 = 31530674
283 + 31530391 = 31530674

Showing the first eight; more decompositions exist.
