Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1010728, here are decompositions:

11 + 1010717 = 1010728
41 + 1010687 = 1010728
101 + 1010627 = 1010728
149 + 1010579 = 1010728
179 + 1010549 = 1010728
227 + 1010501 = 1010728
317 + 1010411 = 1010728
347 + 1010381 = 1010728

Showing the first eight; more decompositions exist.
