Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616236, here are decompositions:

5 + 31616231 = 31616236
17 + 31616219 = 31616236
53 + 31616183 = 31616236
107 + 31616129 = 31616236
167 + 31616069 = 31616236
227 + 31616009 = 31616236
257 + 31615979 = 31616236
263 + 31615973 = 31616236

Showing the first eight; more decompositions exist.
