Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938540, here are decompositions:

3 + 938537 = 938540
7 + 938533 = 938540
103 + 938437 = 938540
181 + 938359 = 938540
193 + 938347 = 938540
199 + 938341 = 938540
277 + 938263 = 938540
283 + 938257 = 938540

Showing the first eight; more decompositions exist.
