Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614884, here are decompositions:

3 + 31614881 = 31614884
31 + 31614853 = 31614884
97 + 31614787 = 31614884
151 + 31614733 = 31614884
181 + 31614703 = 31614884
241 + 31614643 = 31614884
283 + 31614601 = 31614884
337 + 31614547 = 31614884

Showing the first eight; more decompositions exist.
