Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667400, here are decompositions:

23 + 8667377 = 8667400
29 + 8667371 = 8667400
101 + 8667299 = 8667400
173 + 8667227 = 8667400
233 + 8667167 = 8667400
263 + 8667137 = 8667400
461 + 8666939 = 8667400
509 + 8666891 = 8667400

Showing the first eight; more decompositions exist.
