Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666342, here are decompositions:

19 + 8666323 = 8666342
73 + 8666269 = 8666342
283 + 8666059 = 8666342
409 + 8665933 = 8666342
691 + 8665651 = 8666342
709 + 8665633 = 8666342
739 + 8665603 = 8666342
1009 + 8665333 = 8666342

Showing the first eight; more decompositions exist.
