Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616012, here are decompositions:

3 + 31616009 = 31616012
13 + 31615999 = 31616012
19 + 31615993 = 31616012
61 + 31615951 = 31616012
163 + 31615849 = 31616012
229 + 31615783 = 31616012
271 + 31615741 = 31616012
283 + 31615729 = 31616012

Showing the first eight; more decompositions exist.
