Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669978, here are decompositions:

67 + 8669911 = 8669978
157 + 8669821 = 8669978
211 + 8669767 = 8669978
277 + 8669701 = 8669978
307 + 8669671 = 8669978
349 + 8669629 = 8669978
367 + 8669611 = 8669978
661 + 8669317 = 8669978

Showing the first eight; more decompositions exist.
