Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667320, here are decompositions:

7 + 8667313 = 8667320
19 + 8667301 = 8667320
31 + 8667289 = 8667320
199 + 8667121 = 8667320
241 + 8667079 = 8667320
331 + 8666989 = 8667320
367 + 8666953 = 8667320
439 + 8666881 = 8667320

Showing the first eight; more decompositions exist.
