Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667658, here are decompositions:

5 + 8667653 = 8667658
17 + 8667641 = 8667658
47 + 8667611 = 8667658
137 + 8667521 = 8667658
227 + 8667431 = 8667658
239 + 8667419 = 8667658
281 + 8667377 = 8667658
359 + 8667299 = 8667658

Showing the first eight; more decompositions exist.
