Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616248, here are decompositions:

17 + 31616231 = 31616248
29 + 31616219 = 31616248
179 + 31616069 = 31616248
227 + 31616021 = 31616248
239 + 31616009 = 31616248
269 + 31615979 = 31616248
401 + 31615847 = 31616248
491 + 31615757 = 31616248

Showing the first eight; more decompositions exist.
