Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 543978, here are decompositions:

7 + 543971 = 543978
11 + 543967 = 543978
67 + 543911 = 543978
89 + 543889 = 543978
101 + 543877 = 543978
107 + 543871 = 543978
137 + 543841 = 543978
151 + 543827 = 543978

Showing the first eight; more decompositions exist.
