Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616246, here are decompositions:

73 + 31616173 = 31616246
97 + 31616149 = 31616246
199 + 31616047 = 31616246
223 + 31616023 = 31616246
229 + 31616017 = 31616246
397 + 31615849 = 31616246
439 + 31615807 = 31616246
463 + 31615783 = 31616246

Showing the first eight; more decompositions exist.
