Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667256, here are decompositions:

29 + 8667227 = 8667256
89 + 8667167 = 8667256
263 + 8666993 = 8667256
317 + 8666939 = 8667256
449 + 8666807 = 8667256
509 + 8666747 = 8667256
659 + 8666597 = 8667256
743 + 8666513 = 8667256

Showing the first eight; more decompositions exist.
