Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616368, here are decompositions:

5 + 31616363 = 31616368
29 + 31616339 = 31616368
41 + 31616327 = 31616368
71 + 31616297 = 31616368
107 + 31616261 = 31616368
137 + 31616231 = 31616368
149 + 31616219 = 31616368
239 + 31616129 = 31616368

Showing the first eight; more decompositions exist.
