Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025148, here are decompositions:

11 + 1025137 = 1025148
29 + 1025119 = 1025148
37 + 1025111 = 1025148
67 + 1025081 = 1025148
101 + 1025047 = 1025148
109 + 1025039 = 1025148
127 + 1025021 = 1025148
139 + 1025009 = 1025148

Showing the first eight; more decompositions exist.
