Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616358, here are decompositions:

19 + 31616339 = 31616358
31 + 31616327 = 31616358
61 + 31616297 = 31616358
71 + 31616287 = 31616358
97 + 31616261 = 31616358
101 + 31616257 = 31616358
107 + 31616251 = 31616358
127 + 31616231 = 31616358

Showing the first eight; more decompositions exist.
