Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56778, here are decompositions:

5 + 56773 = 56778
11 + 56767 = 56778
31 + 56747 = 56778
41 + 56737 = 56778
47 + 56731 = 56778
67 + 56711 = 56778
97 + 56681 = 56778
107 + 56671 = 56778

Showing the first eight; more decompositions exist.
