Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613494, here are decompositions:

53 + 31613441 = 31613494
83 + 31613411 = 31613494
137 + 31613357 = 31613494
251 + 31613243 = 31613494
467 + 31613027 = 31613494
503 + 31612991 = 31613494
641 + 31612853 = 31613494
761 + 31612733 = 31613494

Showing the first eight; more decompositions exist.
