Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667220, here are decompositions:

41 + 8667179 = 8667220
53 + 8667167 = 8667220
83 + 8667137 = 8667220
227 + 8666993 = 8667220
281 + 8666939 = 8667220
293 + 8666927 = 8667220
509 + 8666711 = 8667220
593 + 8666627 = 8667220

Showing the first eight; more decompositions exist.
