Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668090, here are decompositions:

17 + 8668073 = 8668090
23 + 8668067 = 8668090
29 + 8668061 = 8668090
47 + 8668043 = 8668090
59 + 8668031 = 8668090
89 + 8668001 = 8668090
191 + 8667899 = 8668090
227 + 8667863 = 8668090

Showing the first eight; more decompositions exist.
