Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045656, here are decompositions:

5 + 1045651 = 1045656
13 + 1045643 = 1045656
23 + 1045633 = 1045656
83 + 1045573 = 1045656
97 + 1045559 = 1045656
107 + 1045549 = 1045656
109 + 1045547 = 1045656
113 + 1045543 = 1045656

Showing the first eight; more decompositions exist.
