Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708680, here are decompositions:

17 + 8708663 = 8708680
23 + 8708657 = 8708680
41 + 8708639 = 8708680
53 + 8708627 = 8708680
59 + 8708621 = 8708680
89 + 8708591 = 8708680
173 + 8708507 = 8708680
179 + 8708501 = 8708680

Showing the first eight; more decompositions exist.
