Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938912, here are decompositions:

31 + 938881 = 938912
43 + 938869 = 938912
109 + 938803 = 938912
151 + 938761 = 938912
199 + 938713 = 938912
349 + 938563 = 938912
379 + 938533 = 938912
421 + 938491 = 938912

Showing the first eight; more decompositions exist.
