Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616494, here are decompositions:

71 + 31616423 = 31616494
83 + 31616411 = 31616494
101 + 31616393 = 31616494
113 + 31616381 = 31616494
131 + 31616363 = 31616494
167 + 31616327 = 31616494
197 + 31616297 = 31616494
233 + 31616261 = 31616494

Showing the first eight; more decompositions exist.
