Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614980, here are decompositions:

37 + 31614943 = 31614980
127 + 31614853 = 31614980
151 + 31614829 = 31614980
193 + 31614787 = 31614980
211 + 31614769 = 31614980
277 + 31614703 = 31614980
283 + 31614697 = 31614980
337 + 31614643 = 31614980

Showing the first eight; more decompositions exist.
