Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530076, here are decompositions:

47 + 31530029 = 31530076
59 + 31530017 = 31530076
107 + 31529969 = 31530076
233 + 31529843 = 31530076
257 + 31529819 = 31530076
293 + 31529783 = 31530076
359 + 31529717 = 31530076
509 + 31529567 = 31530076

Showing the first eight; more decompositions exist.
