Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716644, here are decompositions:

5 + 8716639 = 8716644
17 + 8716627 = 8716644
31 + 8716613 = 8716644
61 + 8716583 = 8716644
113 + 8716531 = 8716644
191 + 8716453 = 8716644
193 + 8716451 = 8716644
197 + 8716447 = 8716644

Showing the first eight; more decompositions exist.
