Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668500, here are decompositions:

11 + 8668489 = 8668500
17 + 8668483 = 8668500
41 + 8668459 = 8668500
79 + 8668421 = 8668500
97 + 8668403 = 8668500
131 + 8668369 = 8668500
151 + 8668349 = 8668500
199 + 8668301 = 8668500

Showing the first eight; more decompositions exist.
