Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040490, here are decompositions:

7 + 1040483 = 1040490
41 + 1040449 = 1040490
43 + 1040447 = 1040490
71 + 1040419 = 1040490
79 + 1040411 = 1040490
83 + 1040407 = 1040490
103 + 1040387 = 1040490
109 + 1040381 = 1040490

Showing the first eight; more decompositions exist.
