Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667528, here are decompositions:

7 + 8667521 = 8667528
17 + 8667511 = 8667528
31 + 8667497 = 8667528
71 + 8667457 = 8667528
97 + 8667431 = 8667528
101 + 8667427 = 8667528
109 + 8667419 = 8667528
151 + 8667377 = 8667528

Showing the first eight; more decompositions exist.
