Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667506, here are decompositions:

79 + 8667427 = 8667506
103 + 8667403 = 8667506
157 + 8667349 = 8667506
193 + 8667313 = 8667506
643 + 8666863 = 8667506
709 + 8666797 = 8667506
733 + 8666773 = 8667506
739 + 8666767 = 8667506

Showing the first eight; more decompositions exist.
