Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669146, here are decompositions:

23 + 8669123 = 8669146
29 + 8669117 = 8669146
173 + 8668973 = 8669146
179 + 8668967 = 8669146
257 + 8668889 = 8669146
347 + 8668799 = 8669146
383 + 8668763 = 8669146
449 + 8668697 = 8669146

Showing the first eight; more decompositions exist.
