Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024820, here are decompositions:

37 + 1024783 = 1024820
109 + 1024711 = 1024820
127 + 1024693 = 1024820
151 + 1024669 = 1024820
157 + 1024663 = 1024820
211 + 1024609 = 1024820
229 + 1024591 = 1024820
241 + 1024579 = 1024820

Showing the first eight; more decompositions exist.
