Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56820, here are decompositions:

7 + 56813 = 56820
11 + 56809 = 56820
13 + 56807 = 56820
37 + 56783 = 56820
41 + 56779 = 56820
47 + 56773 = 56820
53 + 56767 = 56820
73 + 56747 = 56820

Showing the first eight; more decompositions exist.
