Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026438, here are decompositions:

11 + 1026427 = 1026438
31 + 1026407 = 1026438
37 + 1026401 = 1026438
47 + 1026391 = 1026438
67 + 1026371 = 1026438
79 + 1026359 = 1026438
107 + 1026331 = 1026438
139 + 1026299 = 1026438

Showing the first eight; more decompositions exist.
