Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614938, here are decompositions:

79 + 31614859 = 31614938
109 + 31614829 = 31614938
151 + 31614787 = 31614938
241 + 31614697 = 31614938
307 + 31614631 = 31614938
337 + 31614601 = 31614938
379 + 31614559 = 31614938
661 + 31614277 = 31614938

Showing the first eight; more decompositions exist.
