Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699918, here are decompositions:

61 + 8699857 = 8699918
67 + 8699851 = 8699918
277 + 8699641 = 8699918
307 + 8699611 = 8699918
379 + 8699539 = 8699918
499 + 8699419 = 8699918
607 + 8699311 = 8699918
691 + 8699227 = 8699918

Showing the first eight; more decompositions exist.
