Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616026, here are decompositions:

3 + 31616023 = 31616026
5 + 31616021 = 31616026
17 + 31616009 = 31616026
47 + 31615979 = 31616026
53 + 31615973 = 31616026
107 + 31615919 = 31616026
179 + 31615847 = 31616026
263 + 31615763 = 31616026

Showing the first eight; more decompositions exist.
