Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699818, here are decompositions:

5 + 8699813 = 8699818
11 + 8699807 = 8699818
47 + 8699771 = 8699818
251 + 8699567 = 8699818
317 + 8699501 = 8699818
431 + 8699387 = 8699818
467 + 8699351 = 8699818
509 + 8699309 = 8699818

Showing the first eight; more decompositions exist.
