Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616922, here are decompositions:

5 + 31616917 = 31616922
19 + 31616903 = 31616922
31 + 31616891 = 31616922
83 + 31616839 = 31616922
149 + 31616773 = 31616922
173 + 31616749 = 31616922
193 + 31616729 = 31616922
229 + 31616693 = 31616922

Showing the first eight; more decompositions exist.
