Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048578, here are decompositions:

5 + 1048573 = 1048578
7 + 1048571 = 1048578
19 + 1048559 = 1048578
29 + 1048549 = 1048578
61 + 1048517 = 1048578
71 + 1048507 = 1048578
131 + 1048447 = 1048578
191 + 1048387 = 1048578

Showing the first eight; more decompositions exist.
