Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616416, here are decompositions:

5 + 31616411 = 31616416
23 + 31616393 = 31616416
47 + 31616369 = 31616416
53 + 31616363 = 31616416
89 + 31616327 = 31616416
197 + 31616219 = 31616416
233 + 31616183 = 31616416
347 + 31616069 = 31616416

Showing the first eight; more decompositions exist.
