Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616222, here are decompositions:

3 + 31616219 = 31616222
73 + 31616149 = 31616222
109 + 31616113 = 31616222
163 + 31616059 = 31616222
181 + 31616041 = 31616222
199 + 31616023 = 31616222
223 + 31615999 = 31616222
229 + 31615993 = 31616222

Showing the first eight; more decompositions exist.
