Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938858, here are decompositions:

31 + 938827 = 938858
97 + 938761 = 938858
181 + 938677 = 938858
199 + 938659 = 938858
241 + 938617 = 938858
367 + 938491 = 938858
421 + 938437 = 938858
499 + 938359 = 938858

Showing the first eight; more decompositions exist.
