Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040872, here are decompositions:

11 + 1040861 = 1040872
59 + 1040813 = 1040872
89 + 1040783 = 1040872
101 + 1040771 = 1040872
293 + 1040579 = 1040872
383 + 1040489 = 1040872
389 + 1040483 = 1040872
461 + 1040411 = 1040872

Showing the first eight; more decompositions exist.
