Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614908, here are decompositions:

19 + 31614889 = 31614908
79 + 31614829 = 31614908
139 + 31614769 = 31614908
211 + 31614697 = 31614908
277 + 31614631 = 31614908
307 + 31614601 = 31614908
349 + 31614559 = 31614908
631 + 31614277 = 31614908

Showing the first eight; more decompositions exist.
