Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667390, here are decompositions:

13 + 8667377 = 8667390
19 + 8667371 = 8667390
41 + 8667349 = 8667390
71 + 8667319 = 8667390
89 + 8667301 = 8667390
101 + 8667289 = 8667390
163 + 8667227 = 8667390
211 + 8667179 = 8667390

Showing the first eight; more decompositions exist.
