Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943830, here are decompositions:

11 + 943819 = 943830
29 + 943801 = 943830
31 + 943799 = 943830
47 + 943783 = 943830
53 + 943777 = 943830
61 + 943769 = 943830
67 + 943763 = 943830
73 + 943757 = 943830

Showing the first eight; more decompositions exist.
