Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600978, here are decompositions:

7 + 8600971 = 8600978
19 + 8600959 = 8600978
31 + 8600947 = 8600978
37 + 8600941 = 8600978
79 + 8600899 = 8600978
97 + 8600881 = 8600978
277 + 8600701 = 8600978
349 + 8600629 = 8600978

Showing the first eight; more decompositions exist.
