Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506820, here are decompositions:

11 + 506809 = 506820
23 + 506797 = 506820
29 + 506791 = 506820
37 + 506783 = 506820
47 + 506773 = 506820
89 + 506731 = 506820
131 + 506689 = 506820
137 + 506683 = 506820

Showing the first eight; more decompositions exist.
