Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667550, here are decompositions:

11 + 8667539 = 8667550
29 + 8667521 = 8667550
53 + 8667497 = 8667550
131 + 8667419 = 8667550
137 + 8667413 = 8667550
173 + 8667377 = 8667550
179 + 8667371 = 8667550
251 + 8667299 = 8667550

Showing the first eight; more decompositions exist.
