Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1050820, here are decompositions:

3 + 1050817 = 1050820
47 + 1050773 = 1050820
83 + 1050737 = 1050820
107 + 1050713 = 1050820
227 + 1050593 = 1050820
257 + 1050563 = 1050820
311 + 1050509 = 1050820
317 + 1050503 = 1050820

Showing the first eight; more decompositions exist.
