Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943580, here are decompositions:

13 + 943567 = 943580
37 + 943543 = 943580
103 + 943477 = 943580
109 + 943471 = 943580
151 + 943429 = 943580
193 + 943387 = 943580
223 + 943357 = 943580
277 + 943303 = 943580

Showing the first eight; more decompositions exist.
