Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 943442, here are decompositions:

13 + 943429 = 943442
79 + 943363 = 943442
139 + 943303 = 943442
193 + 943249 = 943442
211 + 943231 = 943442
223 + 943219 = 943442
229 + 943213 = 943442
433 + 943009 = 943442

Showing the first eight; more decompositions exist.
