Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667558, here are decompositions:

19 + 8667539 = 8667558
37 + 8667521 = 8667558
47 + 8667511 = 8667558
61 + 8667497 = 8667558
101 + 8667457 = 8667558
127 + 8667431 = 8667558
131 + 8667427 = 8667558
139 + 8667419 = 8667558

Showing the first eight; more decompositions exist.
