Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 503820, here are decompositions:

17 + 503803 = 503820
29 + 503791 = 503820
41 + 503779 = 503820
43 + 503777 = 503820
67 + 503753 = 503820
103 + 503717 = 503820
113 + 503707 = 503820
157 + 503663 = 503820

Showing the first eight; more decompositions exist.
