Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667664, here are decompositions:

3 + 8667661 = 8667664
11 + 8667653 = 8667664
23 + 8667641 = 8667664
53 + 8667611 = 8667664
101 + 8667563 = 8667664
167 + 8667497 = 8667664
233 + 8667431 = 8667664
251 + 8667413 = 8667664

Showing the first eight; more decompositions exist.
