Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1054820, here are decompositions:

7 + 1054813 = 1054820
97 + 1054723 = 1054820
103 + 1054717 = 1054820
181 + 1054639 = 1054820
199 + 1054621 = 1054820
211 + 1054609 = 1054820
223 + 1054597 = 1054820
271 + 1054549 = 1054820

Showing the first eight; more decompositions exist.
