Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1056820, here are decompositions:

41 + 1056779 = 1056820
47 + 1056773 = 1056820
101 + 1056719 = 1056820
113 + 1056707 = 1056820
179 + 1056641 = 1056820
197 + 1056623 = 1056820
251 + 1056569 = 1056820
257 + 1056563 = 1056820

Showing the first eight; more decompositions exist.
