Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667398, here are decompositions:

79 + 8667319 = 8667398
97 + 8667301 = 8667398
109 + 8667289 = 8667398
127 + 8667271 = 8667398
277 + 8667121 = 8667398
409 + 8666989 = 8667398
601 + 8666797 = 8667398
631 + 8666767 = 8667398

Showing the first eight; more decompositions exist.
