Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613930, here are decompositions:

3 + 31613927 = 31613930
97 + 31613833 = 31613930
211 + 31613719 = 31613930
307 + 31613623 = 31613930
349 + 31613581 = 31613930
379 + 31613551 = 31613930
547 + 31613383 = 31613930
739 + 31613191 = 31613930

Showing the first eight; more decompositions exist.
