Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668042, here are decompositions:

11 + 8668031 = 8668042
41 + 8668001 = 8668042
113 + 8667929 = 8668042
179 + 8667863 = 8668042
233 + 8667809 = 8668042
353 + 8667689 = 8668042
389 + 8667653 = 8668042
401 + 8667641 = 8668042

Showing the first eight; more decompositions exist.
