Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630826, here are decompositions:

5 + 8630821 = 8630826
13 + 8630813 = 8630826
37 + 8630789 = 8630826
47 + 8630779 = 8630826
67 + 8630759 = 8630826
89 + 8630737 = 8630826
157 + 8630669 = 8630826
163 + 8630663 = 8630826

Showing the first eight; more decompositions exist.
