Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616350, here are decompositions:

11 + 31616339 = 31616350
23 + 31616327 = 31616350
53 + 31616297 = 31616350
89 + 31616261 = 31616350
131 + 31616219 = 31616350
167 + 31616183 = 31616350
281 + 31616069 = 31616350
317 + 31616033 = 31616350

Showing the first eight; more decompositions exist.
