Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668012, here are decompositions:

11 + 8668001 = 8668012
83 + 8667929 = 8668012
113 + 8667899 = 8668012
149 + 8667863 = 8668012
191 + 8667821 = 8668012
359 + 8667653 = 8668012
401 + 8667611 = 8668012
449 + 8667563 = 8668012

Showing the first eight; more decompositions exist.
