Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943820, here are decompositions:

19 + 943801 = 943820
37 + 943783 = 943820
43 + 943777 = 943820
79 + 943741 = 943820
127 + 943693 = 943820
277 + 943543 = 943820
349 + 943471 = 943820
433 + 943387 = 943820

Showing the first eight; more decompositions exist.
