Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614720, here are decompositions:

13 + 31614707 = 31614720
17 + 31614703 = 31614720
19 + 31614701 = 31614720
23 + 31614697 = 31614720
43 + 31614677 = 31614720
73 + 31614647 = 31614720
79 + 31614641 = 31614720
89 + 31614631 = 31614720

Showing the first eight; more decompositions exist.
