Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943872, here are decompositions:

23 + 943849 = 943872
29 + 943843 = 943872
31 + 943841 = 943872
53 + 943819 = 943872
71 + 943801 = 943872
73 + 943799 = 943872
89 + 943783 = 943872
103 + 943769 = 943872

Showing the first eight; more decompositions exist.
