Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616056, here are decompositions:

23 + 31616033 = 31616056
47 + 31616009 = 31616056
83 + 31615973 = 31616056
137 + 31615919 = 31616056
293 + 31615763 = 31616056
467 + 31615589 = 31616056
617 + 31615439 = 31616056
653 + 31615403 = 31616056

Showing the first eight; more decompositions exist.
