Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616574, here are decompositions:

5 + 31616569 = 31616574
13 + 31616561 = 31616574
53 + 31616521 = 31616574
151 + 31616423 = 31616574
163 + 31616411 = 31616574
173 + 31616401 = 31616574
181 + 31616393 = 31616574
193 + 31616381 = 31616574

Showing the first eight; more decompositions exist.
