Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616346, here are decompositions:

7 + 31616339 = 31616346
19 + 31616327 = 31616346
59 + 31616287 = 31616346
89 + 31616257 = 31616346
127 + 31616219 = 31616346
163 + 31616183 = 31616346
173 + 31616173 = 31616346
197 + 31616149 = 31616346

Showing the first eight; more decompositions exist.
