Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022320, here are decompositions:

17 + 1022303 = 1022320
29 + 1022291 = 1022320
71 + 1022249 = 1022320
83 + 1022237 = 1022320
137 + 1022183 = 1022320
179 + 1022141 = 1022320
191 + 1022129 = 1022320
197 + 1022123 = 1022320

Showing the first eight; more decompositions exist.
