Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56880, here are decompositions:

7 + 56873 = 56880
23 + 56857 = 56880
37 + 56843 = 56880
53 + 56827 = 56880
59 + 56821 = 56880
67 + 56813 = 56880
71 + 56809 = 56880
73 + 56807 = 56880

Showing the first eight; more decompositions exist.
