Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530094, here are decompositions:

251 + 31529843 = 31530094
311 + 31529783 = 31530094
443 + 31529651 = 31530094
587 + 31529507 = 31530094
647 + 31529447 = 31530094
773 + 31529321 = 31530094
821 + 31529273 = 31530094
881 + 31529213 = 31530094

Showing the first eight; more decompositions exist.
