Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667178, here are decompositions:

11 + 8667167 = 8667178
41 + 8667137 = 8667178
239 + 8666939 = 8667178
251 + 8666927 = 8667178
431 + 8666747 = 8667178
467 + 8666711 = 8667178
587 + 8666591 = 8667178
659 + 8666519 = 8667178

Showing the first eight; more decompositions exist.
