Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613306, here are decompositions:

79 + 31613227 = 31613306
163 + 31613143 = 31613306
199 + 31613107 = 31613306
337 + 31612969 = 31613306
367 + 31612939 = 31613306
433 + 31612873 = 31613306
547 + 31612759 = 31613306
577 + 31612729 = 31613306

Showing the first eight; more decompositions exist.
