Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530350, here are decompositions:

3 + 31530347 = 31530350
139 + 31530211 = 31530350
307 + 31530043 = 31530350
349 + 31530001 = 31530350
373 + 31529977 = 31530350
601 + 31529749 = 31530350
673 + 31529677 = 31530350
727 + 31529623 = 31530350

Showing the first eight; more decompositions exist.
