Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689978, here are decompositions:

29 + 8689949 = 8689978
137 + 8689841 = 8689978
179 + 8689799 = 8689978
251 + 8689727 = 8689978
317 + 8689661 = 8689978
449 + 8689529 = 8689978
659 + 8689319 = 8689978
677 + 8689301 = 8689978

Showing the first eight; more decompositions exist.
