Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938320, here are decompositions:

11 + 938309 = 938320
41 + 938279 = 938320
101 + 938219 = 938320
113 + 938207 = 938320
137 + 938183 = 938320
191 + 938129 = 938320
263 + 938057 = 938320
269 + 938051 = 938320

Showing the first eight; more decompositions exist.
