Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943900, here are decompositions:

29 + 943871 = 943900
59 + 943841 = 943900
101 + 943799 = 943900
131 + 943769 = 943900
137 + 943763 = 943900
149 + 943751 = 943900
263 + 943637 = 943900
311 + 943589 = 943900

Showing the first eight; more decompositions exist.
