Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614072, here are decompositions:

11 + 31614061 = 31614072
53 + 31614019 = 31614072
71 + 31614001 = 31614072
109 + 31613963 = 31614072
211 + 31613861 = 31614072
229 + 31613843 = 31614072
233 + 31613839 = 31614072
239 + 31613833 = 31614072

Showing the first eight; more decompositions exist.
