Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667776, here are decompositions:

43 + 8667733 = 8667776
79 + 8667697 = 8667776
163 + 8667613 = 8667776
349 + 8667427 = 8667776
373 + 8667403 = 8667776
457 + 8667319 = 8667776
463 + 8667313 = 8667776
487 + 8667289 = 8667776

Showing the first eight; more decompositions exist.
