Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668458, here are decompositions:

37 + 8668421 = 8668458
79 + 8668379 = 8668458
89 + 8668369 = 8668458
101 + 8668357 = 8668458
109 + 8668349 = 8668458
157 + 8668301 = 8668458
179 + 8668279 = 8668458
191 + 8668267 = 8668458

Showing the first eight; more decompositions exist.
