Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614726, here are decompositions:

19 + 31614707 = 31614726
23 + 31614703 = 31614726
29 + 31614697 = 31614726
79 + 31614647 = 31614726
83 + 31614643 = 31614726
139 + 31614587 = 31614726
163 + 31614563 = 31614726
167 + 31614559 = 31614726

Showing the first eight; more decompositions exist.
