Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669766, here are decompositions:

97 + 8669669 = 8669766
109 + 8669657 = 8669766
137 + 8669629 = 8669766
139 + 8669627 = 8669766
173 + 8669593 = 8669766
223 + 8669543 = 8669766
239 + 8669527 = 8669766
277 + 8669489 = 8669766

Showing the first eight; more decompositions exist.
