Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699986, here are decompositions:

5 + 8699981 = 8699986
17 + 8699969 = 8699986
107 + 8699879 = 8699986
173 + 8699813 = 8699986
179 + 8699807 = 8699986
233 + 8699753 = 8699986
263 + 8699723 = 8699986
353 + 8699633 = 8699986

Showing the first eight; more decompositions exist.
