Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614564, here are decompositions:

5 + 31614559 = 31614564
13 + 31614551 = 31614564
17 + 31614547 = 31614564
41 + 31614523 = 31614564
71 + 31614493 = 31614564
193 + 31614371 = 31614564
211 + 31614353 = 31614564
281 + 31614283 = 31614564

Showing the first eight; more decompositions exist.
