Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616328, here are decompositions:

31 + 31616297 = 31616328
41 + 31616287 = 31616328
47 + 31616281 = 31616328
67 + 31616261 = 31616328
71 + 31616257 = 31616328
97 + 31616231 = 31616328
109 + 31616219 = 31616328
179 + 31616149 = 31616328

Showing the first eight; more decompositions exist.
