Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667238, here are decompositions:

11 + 8667227 = 8667238
59 + 8667179 = 8667238
71 + 8667167 = 8667238
101 + 8667137 = 8667238
311 + 8666927 = 8667238
347 + 8666891 = 8667238
389 + 8666849 = 8667238
431 + 8666807 = 8667238

Showing the first eight; more decompositions exist.
