Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027158, here are decompositions:

5 + 1027153 = 1027158
19 + 1027139 = 1027158
29 + 1027129 = 1027158
31 + 1027127 = 1027158
61 + 1027097 = 1027158
107 + 1027051 = 1027158
127 + 1027031 = 1027158
131 + 1027027 = 1027158

Showing the first eight; more decompositions exist.
