Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026538, here are decompositions:

17 + 1026521 = 1026538
59 + 1026479 = 1026538
89 + 1026449 = 1026538
131 + 1026407 = 1026538
137 + 1026401 = 1026538
167 + 1026371 = 1026538
179 + 1026359 = 1026538
239 + 1026299 = 1026538

Showing the first eight; more decompositions exist.
