Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614650, here are decompositions:

3 + 31614647 = 31614650
7 + 31614643 = 31614650
19 + 31614631 = 31614650
103 + 31614547 = 31614650
127 + 31614523 = 31614650
157 + 31614493 = 31614650
307 + 31614343 = 31614650
367 + 31614283 = 31614650

Showing the first eight; more decompositions exist.
