Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938728, here are decompositions:

47 + 938681 = 938728
137 + 938591 = 938728
191 + 938537 = 938728
269 + 938459 = 938728
281 + 938447 = 938728
359 + 938369 = 938728
419 + 938309 = 938728
449 + 938279 = 938728

Showing the first eight; more decompositions exist.
