Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617036, here are decompositions:

7 + 31617029 = 31617036
13 + 31617023 = 31617036
23 + 31617013 = 31617036
37 + 31616999 = 31617036
103 + 31616933 = 31617036
107 + 31616929 = 31617036
149 + 31616887 = 31617036
179 + 31616857 = 31617036

Showing the first eight; more decompositions exist.
