Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616658, here are decompositions:

11 + 31616647 = 31616658
79 + 31616579 = 31616658
89 + 31616569 = 31616658
97 + 31616561 = 31616658
137 + 31616521 = 31616658
149 + 31616509 = 31616658
179 + 31616479 = 31616658
239 + 31616419 = 31616658

Showing the first eight; more decompositions exist.
