Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616166, here are decompositions:

17 + 31616149 = 31616166
37 + 31616129 = 31616166
53 + 31616113 = 31616166
97 + 31616069 = 31616166
107 + 31616059 = 31616166
149 + 31616017 = 31616166
157 + 31616009 = 31616166
167 + 31615999 = 31616166

Showing the first eight; more decompositions exist.
