Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617536, here are decompositions:

3 + 31617533 = 31617536
7 + 31617529 = 31617536
43 + 31617493 = 31617536
79 + 31617457 = 31617536
127 + 31617409 = 31617536
157 + 31617379 = 31617536
163 + 31617373 = 31617536
283 + 31617253 = 31617536

Showing the first eight; more decompositions exist.
