Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616876, here are decompositions:

19 + 31616857 = 31616876
37 + 31616839 = 31616876
103 + 31616773 = 31616876
127 + 31616749 = 31616876
199 + 31616677 = 31616876
229 + 31616647 = 31616876
307 + 31616569 = 31616876
337 + 31616539 = 31616876

Showing the first eight; more decompositions exist.
