Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669618, here are decompositions:

7 + 8669611 = 8669618
229 + 8669389 = 8669618
277 + 8669341 = 8669618
367 + 8669251 = 8669618
379 + 8669239 = 8669618
439 + 8669179 = 8669618
547 + 8669071 = 8669618
577 + 8669041 = 8669618

Showing the first eight; more decompositions exist.
