Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616396, here are decompositions:

3 + 31616393 = 31616396
37 + 31616359 = 31616396
109 + 31616287 = 31616396
139 + 31616257 = 31616396
223 + 31616173 = 31616396
283 + 31616113 = 31616396
337 + 31616059 = 31616396
349 + 31616047 = 31616396

Showing the first eight; more decompositions exist.
