Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025856, here are decompositions:

17 + 1025839 = 1025856
37 + 1025819 = 1025856
53 + 1025803 = 1025856
67 + 1025789 = 1025856
89 + 1025767 = 1025856
107 + 1025749 = 1025856
109 + 1025747 = 1025856
149 + 1025707 = 1025856

Showing the first eight; more decompositions exist.
