Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667228, here are decompositions:

61 + 8667167 = 8667228
107 + 8667121 = 8667228
149 + 8667079 = 8667228
239 + 8666989 = 8667228
337 + 8666891 = 8667228
347 + 8666881 = 8667228
379 + 8666849 = 8667228
389 + 8666839 = 8667228

Showing the first eight; more decompositions exist.
