Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645006, here are decompositions:

43 + 8644963 = 8645006
79 + 8644927 = 8645006
103 + 8644903 = 8645006
163 + 8644843 = 8645006
277 + 8644729 = 8645006
283 + 8644723 = 8645006
373 + 8644633 = 8645006
397 + 8644609 = 8645006

Showing the first eight; more decompositions exist.
