Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616334, here are decompositions:

7 + 31616327 = 31616334
37 + 31616297 = 31616334
47 + 31616287 = 31616334
53 + 31616281 = 31616334
73 + 31616261 = 31616334
83 + 31616251 = 31616334
103 + 31616231 = 31616334
151 + 31616183 = 31616334

Showing the first eight; more decompositions exist.
