Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613266, here are decompositions:

17 + 31613249 = 31613266
23 + 31613243 = 31613266
149 + 31613117 = 31613266
239 + 31613027 = 31613266
353 + 31612913 = 31613266
599 + 31612667 = 31613266
647 + 31612619 = 31613266
677 + 31612589 = 31613266

Showing the first eight; more decompositions exist.
