Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025158, here are decompositions:

5 + 1025153 = 1025158
11 + 1025147 = 1025158
47 + 1025111 = 1025158
59 + 1025099 = 1025158
137 + 1025021 = 1025158
149 + 1025009 = 1025158
227 + 1024931 = 1025158
257 + 1024901 = 1025158

Showing the first eight; more decompositions exist.
