Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67638, here are decompositions:

7 + 67631 = 67638
19 + 67619 = 67638
31 + 67607 = 67638
37 + 67601 = 67638
59 + 67579 = 67638
61 + 67577 = 67638
71 + 67567 = 67638
79 + 67559 = 67638

Showing the first eight; more decompositions exist.
