Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026138, here are decompositions:

11 + 1026127 = 1026138
19 + 1026119 = 1026138
37 + 1026101 = 1026138
97 + 1026041 = 1026138
101 + 1026037 = 1026138
107 + 1026031 = 1026138
109 + 1026029 = 1026138
181 + 1025957 = 1026138

Showing the first eight; more decompositions exist.
