Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943280, here are decompositions:

3 + 943277 = 943280
7 + 943273 = 943280
31 + 943249 = 943280
61 + 943219 = 943280
67 + 943213 = 943280
97 + 943183 = 943280
127 + 943153 = 943280
199 + 943081 = 943280

Showing the first eight; more decompositions exist.
