Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025178, here are decompositions:

17 + 1025161 = 1025178
29 + 1025149 = 1025178
31 + 1025147 = 1025178
41 + 1025137 = 1025178
59 + 1025119 = 1025178
67 + 1025111 = 1025178
79 + 1025099 = 1025178
97 + 1025081 = 1025178

Showing the first eight; more decompositions exist.
