Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528492, here are decompositions:

41 + 31528451 = 31528492
59 + 31528433 = 31528492
179 + 31528313 = 31528492
251 + 31528241 = 31528492
263 + 31528229 = 31528492
389 + 31528103 = 31528492
491 + 31528001 = 31528492
971 + 31527521 = 31528492

Showing the first eight; more decompositions exist.
