Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57780, here are decompositions:

7 + 57773 = 57780
29 + 57751 = 57780
43 + 57737 = 57780
53 + 57727 = 57780
61 + 57719 = 57780
67 + 57713 = 57780
71 + 57709 = 57780
83 + 57697 = 57780

Showing the first eight; more decompositions exist.
