Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667760, here are decompositions:

53 + 8667707 = 8667760
71 + 8667689 = 8667760
83 + 8667677 = 8667760
107 + 8667653 = 8667760
149 + 8667611 = 8667760
197 + 8667563 = 8667760
239 + 8667521 = 8667760
263 + 8667497 = 8667760

Showing the first eight; more decompositions exist.
