Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667408, here are decompositions:

5 + 8667403 = 8667408
31 + 8667377 = 8667408
37 + 8667371 = 8667408
59 + 8667349 = 8667408
89 + 8667319 = 8667408
107 + 8667301 = 8667408
109 + 8667299 = 8667408
137 + 8667271 = 8667408

Showing the first eight; more decompositions exist.
