Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530634, here are decompositions:

17 + 31530617 = 31530634
41 + 31530593 = 31530634
137 + 31530497 = 31530634
197 + 31530437 = 31530634
251 + 31530383 = 31530634
257 + 31530377 = 31530634
293 + 31530341 = 31530634
431 + 31530203 = 31530634

Showing the first eight; more decompositions exist.
