Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667678, here are decompositions:

17 + 8667661 = 8667678
37 + 8667641 = 8667678
67 + 8667611 = 8667678
139 + 8667539 = 8667678
157 + 8667521 = 8667678
167 + 8667511 = 8667678
181 + 8667497 = 8667678
251 + 8667427 = 8667678

Showing the first eight; more decompositions exist.
