Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708644, here are decompositions:

5 + 8708639 = 8708644
17 + 8708627 = 8708644
23 + 8708621 = 8708644
53 + 8708591 = 8708644
107 + 8708537 = 8708644
137 + 8708507 = 8708644
233 + 8708411 = 8708644
251 + 8708393 = 8708644

Showing the first eight; more decompositions exist.
