Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616516, here are decompositions:

7 + 31616509 = 31616516
37 + 31616479 = 31616516
97 + 31616419 = 31616516
157 + 31616359 = 31616516
229 + 31616287 = 31616516
367 + 31616149 = 31616516
457 + 31616059 = 31616516
499 + 31616017 = 31616516

Showing the first eight; more decompositions exist.
