Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614816, here are decompositions:

19 + 31614797 = 31614816
29 + 31614787 = 31614816
47 + 31614769 = 31614816
83 + 31614733 = 31614816
109 + 31614707 = 31614816
113 + 31614703 = 31614816
139 + 31614677 = 31614816
173 + 31614643 = 31614816

Showing the first eight; more decompositions exist.
