Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57820, here are decompositions:

11 + 57809 = 57820
17 + 57803 = 57820
29 + 57791 = 57820
47 + 57773 = 57820
83 + 57737 = 57820
89 + 57731 = 57820
101 + 57719 = 57820
107 + 57713 = 57820

Showing the first eight; more decompositions exist.
