Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616376, here are decompositions:

7 + 31616369 = 31616376
13 + 31616363 = 31616376
17 + 31616359 = 31616376
37 + 31616339 = 31616376
79 + 31616297 = 31616376
89 + 31616287 = 31616376
157 + 31616219 = 31616376
193 + 31616183 = 31616376

Showing the first eight; more decompositions exist.
