Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616976, here are decompositions:

43 + 31616933 = 31616976
47 + 31616929 = 31616976
59 + 31616917 = 31616976
73 + 31616903 = 31616976
89 + 31616887 = 31616976
137 + 31616839 = 31616976
227 + 31616749 = 31616976
229 + 31616747 = 31616976

Showing the first eight; more decompositions exist.
