Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 983440, here are decompositions:

11 + 983429 = 983440
113 + 983327 = 983440
173 + 983267 = 983440
179 + 983261 = 983440
197 + 983243 = 983440
251 + 983189 = 983440
317 + 983123 = 983440
467 + 982973 = 983440

Showing the first eight; more decompositions exist.
