Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025166, here are decompositions:

5 + 1025161 = 1025166
13 + 1025153 = 1025166
17 + 1025149 = 1025166
19 + 1025147 = 1025166
29 + 1025137 = 1025166
47 + 1025119 = 1025166
53 + 1025113 = 1025166
67 + 1025099 = 1025166

Showing the first eight; more decompositions exist.
