Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667786, here are decompositions:

53 + 8667733 = 8667786
59 + 8667727 = 8667786
79 + 8667707 = 8667786
89 + 8667697 = 8667786
97 + 8667689 = 8667786
109 + 8667677 = 8667786
173 + 8667613 = 8667786
223 + 8667563 = 8667786

Showing the first eight; more decompositions exist.
