Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616364, here are decompositions:

5 + 31616359 = 31616364
37 + 31616327 = 31616364
67 + 31616297 = 31616364
83 + 31616281 = 31616364
103 + 31616261 = 31616364
107 + 31616257 = 31616364
113 + 31616251 = 31616364
181 + 31616183 = 31616364

Showing the first eight; more decompositions exist.
