Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943940, here are decompositions:

31 + 943909 = 943940
37 + 943903 = 943940
97 + 943843 = 943940
103 + 943837 = 943940
139 + 943801 = 943940
157 + 943783 = 943940
163 + 943777 = 943940
199 + 943741 = 943940

Showing the first eight; more decompositions exist.
