Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616394, here are decompositions:

13 + 31616381 = 31616394
31 + 31616363 = 31616394
67 + 31616327 = 31616394
97 + 31616297 = 31616394
107 + 31616287 = 31616394
113 + 31616281 = 31616394
137 + 31616257 = 31616394
163 + 31616231 = 31616394

Showing the first eight; more decompositions exist.
