Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667660, here are decompositions:

7 + 8667653 = 8667660
19 + 8667641 = 8667660
47 + 8667613 = 8667660
59 + 8667601 = 8667660
97 + 8667563 = 8667660
101 + 8667559 = 8667660
139 + 8667521 = 8667660
149 + 8667511 = 8667660

Showing the first eight; more decompositions exist.
