Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616446, here are decompositions:

23 + 31616423 = 31616446
53 + 31616393 = 31616446
83 + 31616363 = 31616446
107 + 31616339 = 31616446
149 + 31616297 = 31616446
227 + 31616219 = 31616446
263 + 31616183 = 31616446
317 + 31616129 = 31616446

Showing the first eight; more decompositions exist.
