Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669798, here are decompositions:

31 + 8669767 = 8669798
97 + 8669701 = 8669798
127 + 8669671 = 8669798
271 + 8669527 = 8669798
409 + 8669389 = 8669798
457 + 8669341 = 8669798
547 + 8669251 = 8669798
619 + 8669179 = 8669798

Showing the first eight; more decompositions exist.
