Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943978, here are decompositions:

11 + 943967 = 943978
47 + 943931 = 943978
107 + 943871 = 943978
137 + 943841 = 943978
179 + 943799 = 943978
197 + 943781 = 943978
227 + 943751 = 943978
389 + 943589 = 943978

Showing the first eight; more decompositions exist.
