Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616572, here are decompositions:

3 + 31616569 = 31616572
11 + 31616561 = 31616572
149 + 31616423 = 31616572
179 + 31616393 = 31616572
191 + 31616381 = 31616572
233 + 31616339 = 31616572
311 + 31616261 = 31616572
353 + 31616219 = 31616572

Showing the first eight; more decompositions exist.
