Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667668, here are decompositions:

7 + 8667661 = 8667668
67 + 8667601 = 8667668
109 + 8667559 = 8667668
157 + 8667511 = 8667668
211 + 8667457 = 8667668
241 + 8667427 = 8667668
349 + 8667319 = 8667668
367 + 8667301 = 8667668

Showing the first eight; more decompositions exist.
