Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667670, here are decompositions:

17 + 8667653 = 8667670
29 + 8667641 = 8667670
59 + 8667611 = 8667670
107 + 8667563 = 8667670
131 + 8667539 = 8667670
149 + 8667521 = 8667670
173 + 8667497 = 8667670
239 + 8667431 = 8667670

Showing the first eight; more decompositions exist.
