Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616716, here are decompositions:

23 + 31616693 = 31616716
29 + 31616687 = 31616716
113 + 31616603 = 31616716
137 + 31616579 = 31616716
293 + 31616423 = 31616716
347 + 31616369 = 31616716
353 + 31616363 = 31616716
389 + 31616327 = 31616716

Showing the first eight; more decompositions exist.
