Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701644, here are decompositions:

13 + 8701631 = 8701644
23 + 8701621 = 8701644
67 + 8701577 = 8701644
73 + 8701571 = 8701644
113 + 8701531 = 8701644
137 + 8701507 = 8701644
151 + 8701493 = 8701644
167 + 8701477 = 8701644

Showing the first eight; more decompositions exist.
