Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616796, here are decompositions:

23 + 31616773 = 31616796
47 + 31616749 = 31616796
67 + 31616729 = 31616796
89 + 31616707 = 31616796
103 + 31616693 = 31616796
109 + 31616687 = 31616796
149 + 31616647 = 31616796
173 + 31616623 = 31616796

Showing the first eight; more decompositions exist.
