Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668464, here are decompositions:

5 + 8668459 = 8668464
41 + 8668423 = 8668464
43 + 8668421 = 8668464
61 + 8668403 = 8668464
83 + 8668381 = 8668464
97 + 8668367 = 8668464
107 + 8668357 = 8668464
163 + 8668301 = 8668464

Showing the first eight; more decompositions exist.
