Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616202, here are decompositions:

19 + 31616183 = 31616202
29 + 31616173 = 31616202
53 + 31616149 = 31616202
73 + 31616129 = 31616202
89 + 31616113 = 31616202
179 + 31616023 = 31616202
181 + 31616021 = 31616202
193 + 31616009 = 31616202

Showing the first eight; more decompositions exist.
