Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631002, here are decompositions:

19 + 8630983 = 8631002
31 + 8630971 = 8631002
73 + 8630929 = 8631002
103 + 8630899 = 8631002
151 + 8630851 = 8631002
181 + 8630821 = 8631002
223 + 8630779 = 8631002
349 + 8630653 = 8631002

Showing the first eight; more decompositions exist.
