Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616426, here are decompositions:

3 + 31616423 = 31616426
7 + 31616419 = 31616426
67 + 31616359 = 31616426
139 + 31616287 = 31616426
277 + 31616149 = 31616426
313 + 31616113 = 31616426
367 + 31616059 = 31616426
379 + 31616047 = 31616426

Showing the first eight; more decompositions exist.
