Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56680, here are decompositions:

17 + 56663 = 56680
47 + 56633 = 56680
83 + 56597 = 56680
89 + 56591 = 56680
137 + 56543 = 56680
149 + 56531 = 56680
179 + 56501 = 56680
191 + 56489 = 56680

Showing the first eight; more decompositions exist.
