Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1064728, here are decompositions:

29 + 1064699 = 1064728
47 + 1064681 = 1064728
59 + 1064669 = 1064728
179 + 1064549 = 1064728
251 + 1064477 = 1064728
257 + 1064471 = 1064728
317 + 1064411 = 1064728
389 + 1064339 = 1064728

Showing the first eight; more decompositions exist.
