Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614950, here are decompositions:

7 + 31614943 = 31614950
61 + 31614889 = 31614950
97 + 31614853 = 31614950
163 + 31614787 = 31614950
181 + 31614769 = 31614950
307 + 31614643 = 31614950
349 + 31614601 = 31614950
457 + 31614493 = 31614950

Showing the first eight; more decompositions exist.
