Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699618, here are decompositions:

7 + 8699611 = 8699618
61 + 8699557 = 8699618
79 + 8699539 = 8699618
199 + 8699419 = 8699618
229 + 8699389 = 8699618
307 + 8699311 = 8699618
349 + 8699269 = 8699618
379 + 8699239 = 8699618

Showing the first eight; more decompositions exist.
