Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615014, here are decompositions:

7 + 31615007 = 31615014
61 + 31614953 = 31615014
71 + 31614943 = 31615014
73 + 31614941 = 31615014
163 + 31614851 = 31615014
181 + 31614833 = 31615014
227 + 31614787 = 31615014
281 + 31614733 = 31615014

Showing the first eight; more decompositions exist.
