Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616186, here are decompositions:

3 + 31616183 = 31616186
13 + 31616173 = 31616186
37 + 31616149 = 31616186
73 + 31616113 = 31616186
127 + 31616059 = 31616186
139 + 31616047 = 31616186
163 + 31616023 = 31616186
193 + 31615993 = 31616186

Showing the first eight; more decompositions exist.
