Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025170, here are decompositions:

17 + 1025153 = 1025170
23 + 1025147 = 1025170
59 + 1025111 = 1025170
71 + 1025099 = 1025170
89 + 1025081 = 1025170
131 + 1025039 = 1025170
149 + 1025021 = 1025170
173 + 1024997 = 1025170

Showing the first eight; more decompositions exist.
