Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614212, here are decompositions:

13 + 31614199 = 31614212
31 + 31614181 = 31614212
79 + 31614133 = 31614212
103 + 31614109 = 31614212
151 + 31614061 = 31614212
193 + 31614019 = 31614212
211 + 31614001 = 31614212
373 + 31613839 = 31614212

Showing the first eight; more decompositions exist.
