Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530296, here are decompositions:

3 + 31530293 = 31530296
199 + 31530097 = 31530296
373 + 31529923 = 31530296
397 + 31529899 = 31530296
547 + 31529749 = 31530296
619 + 31529677 = 31530296
673 + 31529623 = 31530296
739 + 31529557 = 31530296

Showing the first eight; more decompositions exist.
