Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667538, here are decompositions:

17 + 8667521 = 8667538
41 + 8667497 = 8667538
107 + 8667431 = 8667538
167 + 8667371 = 8667538
239 + 8667299 = 8667538
281 + 8667257 = 8667538
311 + 8667227 = 8667538
359 + 8667179 = 8667538

Showing the first eight; more decompositions exist.
