Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943778, here are decompositions:

37 + 943741 = 943778
79 + 943699 = 943778
127 + 943651 = 943778
211 + 943567 = 943778
307 + 943471 = 943778
349 + 943429 = 943778
421 + 943357 = 943778
457 + 943321 = 943778

Showing the first eight; more decompositions exist.
