Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048820, here are decompositions:

13 + 1048807 = 1048820
37 + 1048783 = 1048820
61 + 1048759 = 1048820
103 + 1048717 = 1048820
139 + 1048681 = 1048820
193 + 1048627 = 1048820
211 + 1048609 = 1048820
271 + 1048549 = 1048820

Showing the first eight; more decompositions exist.
