Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667662, here are decompositions:

61 + 8667601 = 8667662
103 + 8667559 = 8667662
151 + 8667511 = 8667662
313 + 8667349 = 8667662
349 + 8667313 = 8667662
373 + 8667289 = 8667662
541 + 8667121 = 8667662
673 + 8666989 = 8667662

Showing the first eight; more decompositions exist.
