Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699824, here are decompositions:

11 + 8699813 = 8699824
17 + 8699807 = 8699824
53 + 8699771 = 8699824
71 + 8699753 = 8699824
101 + 8699723 = 8699824
191 + 8699633 = 8699824
251 + 8699573 = 8699824
257 + 8699567 = 8699824

Showing the first eight; more decompositions exist.
