Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43778, here are decompositions:

19 + 43759 = 43778
61 + 43717 = 43778
67 + 43711 = 43778
109 + 43669 = 43778
127 + 43651 = 43778
151 + 43627 = 43778
181 + 43597 = 43778
199 + 43579 = 43778

Showing the first eight; more decompositions exist.
