Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614622, here are decompositions:

59 + 31614563 = 31614622
71 + 31614551 = 31614622
173 + 31614449 = 31614622
251 + 31614371 = 31614622
269 + 31614353 = 31614622
443 + 31614179 = 31614622
449 + 31614173 = 31614622
461 + 31614161 = 31614622

Showing the first eight; more decompositions exist.
