Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943400, here are decompositions:

13 + 943387 = 943400
37 + 943363 = 943400
43 + 943357 = 943400
79 + 943321 = 943400
97 + 943303 = 943400
127 + 943273 = 943400
151 + 943249 = 943400
181 + 943219 = 943400

Showing the first eight; more decompositions exist.
