Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630802, here are decompositions:

13 + 8630789 = 8630802
23 + 8630779 = 8630802
31 + 8630771 = 8630802
43 + 8630759 = 8630802
53 + 8630749 = 8630802
139 + 8630663 = 8630802
149 + 8630653 = 8630802
163 + 8630639 = 8630802

Showing the first eight; more decompositions exist.
