Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040728, here are decompositions:

11 + 1040717 = 1040728
71 + 1040657 = 1040728
131 + 1040597 = 1040728
149 + 1040579 = 1040728
197 + 1040531 = 1040728
239 + 1040489 = 1040728
281 + 1040447 = 1040728
317 + 1040411 = 1040728

Showing the first eight; more decompositions exist.
