Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943870, here are decompositions:

29 + 943841 = 943870
71 + 943799 = 943870
89 + 943781 = 943870
101 + 943769 = 943870
107 + 943763 = 943870
113 + 943757 = 943870
233 + 943637 = 943870
269 + 943601 = 943870

Showing the first eight; more decompositions exist.
