Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943782, here are decompositions:

5 + 943777 = 943782
13 + 943769 = 943782
19 + 943763 = 943782
31 + 943751 = 943782
41 + 943741 = 943782
53 + 943729 = 943782
83 + 943699 = 943782
89 + 943693 = 943782

Showing the first eight; more decompositions exist.
