Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668446, here are decompositions:

23 + 8668423 = 8668446
43 + 8668403 = 8668446
67 + 8668379 = 8668446
79 + 8668367 = 8668446
89 + 8668357 = 8668446
97 + 8668349 = 8668446
167 + 8668279 = 8668446
173 + 8668273 = 8668446

Showing the first eight; more decompositions exist.
