Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943938, here are decompositions:

7 + 943931 = 943938
29 + 943909 = 943938
67 + 943871 = 943938
89 + 943849 = 943938
97 + 943841 = 943938
101 + 943837 = 943938
137 + 943801 = 943938
139 + 943799 = 943938

Showing the first eight; more decompositions exist.
