Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667638, here are decompositions:

37 + 8667601 = 8667638
79 + 8667559 = 8667638
127 + 8667511 = 8667638
181 + 8667457 = 8667638
211 + 8667427 = 8667638
337 + 8667301 = 8667638
349 + 8667289 = 8667638
367 + 8667271 = 8667638

Showing the first eight; more decompositions exist.
