Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10638, here are decompositions:

7 + 10631 = 10638
11 + 10627 = 10638
31 + 10607 = 10638
37 + 10601 = 10638
41 + 10597 = 10638
71 + 10567 = 10638
79 + 10559 = 10638
107 + 10531 = 10638

Showing the first eight; more decompositions exist.
