Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669216, here are decompositions:

37 + 8669179 = 8669216
103 + 8669113 = 8669216
109 + 8669107 = 8669216
223 + 8668993 = 8669216
379 + 8668837 = 8669216
433 + 8668783 = 8669216
607 + 8668609 = 8669216
727 + 8668489 = 8669216

Showing the first eight; more decompositions exist.
