Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616644, here are decompositions:

41 + 31616603 = 31616644
83 + 31616561 = 31616644
233 + 31616411 = 31616644
251 + 31616393 = 31616644
263 + 31616381 = 31616644
281 + 31616363 = 31616644
317 + 31616327 = 31616644
347 + 31616297 = 31616644

Showing the first eight; more decompositions exist.
