Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530496, here are decompositions:

17 + 31530479 = 31530496
59 + 31530437 = 31530496
113 + 31530383 = 31530496
149 + 31530347 = 31530496
227 + 31530269 = 31530496
293 + 31530203 = 31530496
353 + 31530143 = 31530496
467 + 31530029 = 31530496

Showing the first eight; more decompositions exist.
