Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017772, here are decompositions:

23 + 1017749 = 1017772
53 + 1017719 = 1017772
59 + 1017713 = 1017772
89 + 1017683 = 1017772
149 + 1017623 = 1017772
233 + 1017539 = 1017772
293 + 1017479 = 1017772
389 + 1017383 = 1017772

Showing the first eight; more decompositions exist.
