Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530914, here are decompositions:

13 + 31530901 = 31530914
73 + 31530841 = 31530914
211 + 31530703 = 31530914
271 + 31530643 = 31530914
277 + 31530637 = 31530914
307 + 31530607 = 31530914
463 + 31530451 = 31530914
523 + 31530391 = 31530914

Showing the first eight; more decompositions exist.
