Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666832, here are decompositions:

23 + 8666809 = 8666832
59 + 8666773 = 8666832
149 + 8666683 = 8666832
151 + 8666681 = 8666832
241 + 8666591 = 8666832
313 + 8666519 = 8666832
331 + 8666501 = 8666832
353 + 8666479 = 8666832

Showing the first eight; more decompositions exist.
