Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667906, here are decompositions:

7 + 8667899 = 8667906
43 + 8667863 = 8667906
59 + 8667847 = 8667906
97 + 8667809 = 8667906
109 + 8667797 = 8667906
113 + 8667793 = 8667906
173 + 8667733 = 8667906
179 + 8667727 = 8667906

Showing the first eight; more decompositions exist.
