Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026156, here are decompositions:

13 + 1026143 = 1026156
17 + 1026139 = 1026156
29 + 1026127 = 1026156
37 + 1026119 = 1026156
83 + 1026073 = 1026156
113 + 1026043 = 1026156
127 + 1026029 = 1026156
199 + 1025957 = 1026156

Showing the first eight; more decompositions exist.
