Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040540, here are decompositions:

19 + 1040521 = 1040540
37 + 1040503 = 1040540
229 + 1040311 = 1040540
313 + 1040227 = 1040540
337 + 1040203 = 1040540
349 + 1040191 = 1040540
373 + 1040167 = 1040540
379 + 1040161 = 1040540

Showing the first eight; more decompositions exist.
