Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938836, here are decompositions:

5 + 938831 = 938836
29 + 938807 = 938836
89 + 938747 = 938836
263 + 938573 = 938836
383 + 938453 = 938836
389 + 938447 = 938836
443 + 938393 = 938836
449 + 938387 = 938836

Showing the first eight; more decompositions exist.
