Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615010, here are decompositions:

3 + 31615007 = 31615010
67 + 31614943 = 31615010
151 + 31614859 = 31615010
157 + 31614853 = 31615010
181 + 31614829 = 31615010
223 + 31614787 = 31615010
241 + 31614769 = 31615010
277 + 31614733 = 31615010

Showing the first eight; more decompositions exist.
