Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943780, here are decompositions:

3 + 943777 = 943780
11 + 943769 = 943780
17 + 943763 = 943780
23 + 943757 = 943780
29 + 943751 = 943780
179 + 943601 = 943780
191 + 943589 = 943780
239 + 943541 = 943780

Showing the first eight; more decompositions exist.
