Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667806, here are decompositions:

13 + 8667793 = 8667806
73 + 8667733 = 8667806
79 + 8667727 = 8667806
109 + 8667697 = 8667806
193 + 8667613 = 8667806
349 + 8667457 = 8667806
379 + 8667427 = 8667806
457 + 8667349 = 8667806

Showing the first eight; more decompositions exist.
