Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943220, here are decompositions:

7 + 943213 = 943220
37 + 943183 = 943220
67 + 943153 = 943220
139 + 943081 = 943220
163 + 943057 = 943220
211 + 943009 = 943220
241 + 942979 = 943220
277 + 942943 = 943220

Showing the first eight; more decompositions exist.
