Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668426, here are decompositions:

3 + 8668423 = 8668426
5 + 8668421 = 8668426
23 + 8668403 = 8668426
47 + 8668379 = 8668426
59 + 8668367 = 8668426
233 + 8668193 = 8668426
269 + 8668157 = 8668426
293 + 8668133 = 8668426

Showing the first eight; more decompositions exist.
