Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614678, here are decompositions:

31 + 31614647 = 31614678
37 + 31614641 = 31614678
47 + 31614631 = 31614678
127 + 31614551 = 31614678
131 + 31614547 = 31614678
229 + 31614449 = 31614678
307 + 31614371 = 31614678
401 + 31614277 = 31614678

Showing the first eight; more decompositions exist.
