Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56978, here are decompositions:

37 + 56941 = 56978
67 + 56911 = 56978
151 + 56827 = 56978
157 + 56821 = 56978
199 + 56779 = 56978
211 + 56767 = 56978
241 + 56737 = 56978
277 + 56701 = 56978

Showing the first eight; more decompositions exist.
