Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616808, here are decompositions:

59 + 31616749 = 31616808
61 + 31616747 = 31616808
79 + 31616729 = 31616808
101 + 31616707 = 31616808
131 + 31616677 = 31616808
137 + 31616671 = 31616808
229 + 31616579 = 31616808
239 + 31616569 = 31616808

Showing the first eight; more decompositions exist.
