Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699978, here are decompositions:

19 + 8699959 = 8699978
31 + 8699947 = 8699978
61 + 8699917 = 8699978
127 + 8699851 = 8699978
151 + 8699827 = 8699978
337 + 8699641 = 8699978
367 + 8699611 = 8699978
421 + 8699557 = 8699978

Showing the first eight; more decompositions exist.
