Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713644, here are decompositions:

13 + 8713631 = 8713644
41 + 8713603 = 8713644
53 + 8713591 = 8713644
61 + 8713583 = 8713644
67 + 8713577 = 8713644
97 + 8713547 = 8713644
113 + 8713531 = 8713644
131 + 8713513 = 8713644

Showing the first eight; more decompositions exist.
