Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516334, here are decompositions:

7 + 31516327 = 31516334
37 + 31516297 = 31516334
97 + 31516237 = 31516334
151 + 31516183 = 31516334
181 + 31516153 = 31516334
211 + 31516123 = 31516334
307 + 31516027 = 31516334
313 + 31516021 = 31516334

Showing the first eight; more decompositions exist.
