Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043390, here are decompositions:

13 + 1043377 = 1043390
67 + 1043323 = 1043390
79 + 1043311 = 1043390
97 + 1043293 = 1043390
181 + 1043209 = 1043390
199 + 1043191 = 1043390
223 + 1043167 = 1043390
277 + 1043113 = 1043390

Showing the first eight; more decompositions exist.
