Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616398, here are decompositions:

5 + 31616393 = 31616398
17 + 31616381 = 31616398
29 + 31616369 = 31616398
59 + 31616339 = 31616398
71 + 31616327 = 31616398
101 + 31616297 = 31616398
137 + 31616261 = 31616398
167 + 31616231 = 31616398

Showing the first eight; more decompositions exist.
