Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667612, here are decompositions:

11 + 8667601 = 8667612
53 + 8667559 = 8667612
73 + 8667539 = 8667612
101 + 8667511 = 8667612
181 + 8667431 = 8667612
193 + 8667419 = 8667612
199 + 8667413 = 8667612
241 + 8667371 = 8667612

Showing the first eight; more decompositions exist.
