Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667378, here are decompositions:

7 + 8667371 = 8667378
29 + 8667349 = 8667378
59 + 8667319 = 8667378
79 + 8667299 = 8667378
89 + 8667289 = 8667378
107 + 8667271 = 8667378
151 + 8667227 = 8667378
199 + 8667179 = 8667378

Showing the first eight; more decompositions exist.
