Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669720, here are decompositions:

19 + 8669701 = 8669720
97 + 8669623 = 8669720
109 + 8669611 = 8669720
127 + 8669593 = 8669720
193 + 8669527 = 8669720
277 + 8669443 = 8669720
331 + 8669389 = 8669720
379 + 8669341 = 8669720

Showing the first eight; more decompositions exist.
