Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616484, here are decompositions:

5 + 31616479 = 31616484
61 + 31616423 = 31616484
73 + 31616411 = 31616484
83 + 31616401 = 31616484
103 + 31616381 = 31616484
157 + 31616327 = 31616484
197 + 31616287 = 31616484
223 + 31616261 = 31616484

Showing the first eight; more decompositions exist.
