Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621616, here are decompositions:

7 + 8621609 = 8621616
137 + 8621479 = 8621616
139 + 8621477 = 8621616
149 + 8621467 = 8621616
163 + 8621453 = 8621616
173 + 8621443 = 8621616
239 + 8621377 = 8621616
277 + 8621339 = 8621616

Showing the first eight; more decompositions exist.
