Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616266, here are decompositions:

5 + 31616261 = 31616266
47 + 31616219 = 31616266
83 + 31616183 = 31616266
137 + 31616129 = 31616266
197 + 31616069 = 31616266
233 + 31616033 = 31616266
257 + 31616009 = 31616266
293 + 31615973 = 31616266

Showing the first eight; more decompositions exist.
