Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616896, here are decompositions:

5 + 31616891 = 31616896
149 + 31616747 = 31616896
167 + 31616729 = 31616896
293 + 31616603 = 31616896
317 + 31616579 = 31616896
503 + 31616393 = 31616896
557 + 31616339 = 31616896
569 + 31616327 = 31616896

Showing the first eight; more decompositions exist.
