Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615166, here are decompositions:

3 + 31615163 = 31615166
13 + 31615153 = 31615166
103 + 31615063 = 31615166
127 + 31615039 = 31615166
223 + 31614943 = 31615166
277 + 31614889 = 31615166
307 + 31614859 = 31615166
313 + 31614853 = 31615166

Showing the first eight; more decompositions exist.
