Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667560, here are decompositions:

103 + 8667457 = 8667560
157 + 8667403 = 8667560
211 + 8667349 = 8667560
241 + 8667319 = 8667560
271 + 8667289 = 8667560
409 + 8667151 = 8667560
439 + 8667121 = 8667560
457 + 8667103 = 8667560

Showing the first eight; more decompositions exist.
