Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667438, here are decompositions:

7 + 8667431 = 8667438
11 + 8667427 = 8667438
19 + 8667419 = 8667438
61 + 8667377 = 8667438
67 + 8667371 = 8667438
89 + 8667349 = 8667438
137 + 8667301 = 8667438
139 + 8667299 = 8667438

Showing the first eight; more decompositions exist.
