Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616422, here are decompositions:

3 + 31616419 = 31616422
11 + 31616411 = 31616422
29 + 31616393 = 31616422
41 + 31616381 = 31616422
53 + 31616369 = 31616422
59 + 31616363 = 31616422
83 + 31616339 = 31616422
191 + 31616231 = 31616422

Showing the first eight; more decompositions exist.
