Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614730, here are decompositions:

23 + 31614707 = 31614730
29 + 31614701 = 31614730
53 + 31614677 = 31614730
83 + 31614647 = 31614730
89 + 31614641 = 31614730
167 + 31614563 = 31614730
179 + 31614551 = 31614730
281 + 31614449 = 31614730

Showing the first eight; more decompositions exist.
