Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031728, here are decompositions:

11 + 1031717 = 1031728
59 + 1031669 = 1031728
167 + 1031561 = 1031728
179 + 1031549 = 1031728
197 + 1031531 = 1031728
239 + 1031489 = 1031728
251 + 1031477 = 1031728
281 + 1031447 = 1031728

Showing the first eight; more decompositions exist.
