Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943812, here are decompositions:

11 + 943801 = 943812
13 + 943799 = 943812
29 + 943783 = 943812
31 + 943781 = 943812
43 + 943769 = 943812
61 + 943751 = 943812
71 + 943741 = 943812
83 + 943729 = 943812

Showing the first eight; more decompositions exist.
