Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667808, here are decompositions:

11 + 8667797 = 8667808
101 + 8667707 = 8667808
131 + 8667677 = 8667808
167 + 8667641 = 8667808
197 + 8667611 = 8667808
269 + 8667539 = 8667808
311 + 8667497 = 8667808
389 + 8667419 = 8667808

Showing the first eight; more decompositions exist.
