Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614382, here are decompositions:

5 + 31614377 = 31614382
11 + 31614371 = 31614382
29 + 31614353 = 31614382
311 + 31614071 = 31614382
419 + 31613963 = 31614382
521 + 31613861 = 31614382
563 + 31613819 = 31614382
599 + 31613783 = 31614382

Showing the first eight; more decompositions exist.
