Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669170, here are decompositions:

11 + 8669159 = 8669170
47 + 8669123 = 8669170
53 + 8669117 = 8669170
197 + 8668973 = 8669170
269 + 8668901 = 8669170
281 + 8668889 = 8669170
353 + 8668817 = 8669170
431 + 8668739 = 8669170

Showing the first eight; more decompositions exist.
