Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026140, here are decompositions:

13 + 1026127 = 1026140
67 + 1026073 = 1026140
79 + 1026061 = 1026140
97 + 1026043 = 1026140
103 + 1026037 = 1026140
109 + 1026031 = 1026140
211 + 1025929 = 1026140
223 + 1025917 = 1026140

Showing the first eight; more decompositions exist.
