Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667616, here are decompositions:

3 + 8667613 = 8667616
5 + 8667611 = 8667616
53 + 8667563 = 8667616
197 + 8667419 = 8667616
239 + 8667377 = 8667616
317 + 8667299 = 8667616
359 + 8667257 = 8667616
389 + 8667227 = 8667616

Showing the first eight; more decompositions exist.
