Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943878, here are decompositions:

7 + 943871 = 943878
29 + 943849 = 943878
37 + 943841 = 943878
41 + 943837 = 943878
59 + 943819 = 943878
79 + 943799 = 943878
97 + 943781 = 943878
101 + 943777 = 943878

Showing the first eight; more decompositions exist.
