Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616338, here are decompositions:

11 + 31616327 = 31616338
41 + 31616297 = 31616338
107 + 31616231 = 31616338
269 + 31616069 = 31616338
317 + 31616021 = 31616338
359 + 31615979 = 31616338
419 + 31615919 = 31616338
491 + 31615847 = 31616338

Showing the first eight; more decompositions exist.
