Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040648, here are decompositions:

19 + 1040629 = 1040648
67 + 1040581 = 1040648
127 + 1040521 = 1040648
199 + 1040449 = 1040648
229 + 1040419 = 1040648
241 + 1040407 = 1040648
277 + 1040371 = 1040648
337 + 1040311 = 1040648

Showing the first eight; more decompositions exist.
