Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 937638, here are decompositions:

5 + 937633 = 937638
11 + 937627 = 937638
47 + 937591 = 937638
61 + 937577 = 937638
67 + 937571 = 937638
101 + 937537 = 937638
127 + 937511 = 937638
137 + 937501 = 937638

Showing the first eight; more decompositions exist.
