Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667928, here are decompositions:

29 + 8667899 = 8667928
107 + 8667821 = 8667928
131 + 8667797 = 8667928
239 + 8667689 = 8667928
251 + 8667677 = 8667928
317 + 8667611 = 8667928
389 + 8667539 = 8667928
431 + 8667497 = 8667928

Showing the first eight; more decompositions exist.
