Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616184, here are decompositions:

11 + 31616173 = 31616184
71 + 31616113 = 31616184
137 + 31616047 = 31616184
151 + 31616033 = 31616184
163 + 31616021 = 31616184
167 + 31616017 = 31616184
191 + 31615993 = 31616184
211 + 31615973 = 31616184

Showing the first eight; more decompositions exist.
