Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613476, here are decompositions:

227 + 31613249 = 31613476
233 + 31613243 = 31613476
359 + 31613117 = 31613476
449 + 31613027 = 31613476
563 + 31612913 = 31613476
743 + 31612733 = 31613476
809 + 31612667 = 31613476
857 + 31612619 = 31613476

Showing the first eight; more decompositions exist.
