Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530124, here are decompositions:

107 + 31530017 = 31530124
191 + 31529933 = 31530124
233 + 31529891 = 31530124
281 + 31529843 = 31530124
443 + 31529681 = 31530124
557 + 31529567 = 31530124
617 + 31529507 = 31530124
653 + 31529471 = 31530124

Showing the first eight; more decompositions exist.
