Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616226, here are decompositions:

7 + 31616219 = 31616226
43 + 31616183 = 31616226
53 + 31616173 = 31616226
97 + 31616129 = 31616226
113 + 31616113 = 31616226
157 + 31616069 = 31616226
167 + 31616059 = 31616226
179 + 31616047 = 31616226

Showing the first eight; more decompositions exist.
