Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026090, here are decompositions:

17 + 1026073 = 1026090
29 + 1026061 = 1026090
47 + 1026043 = 1026090
53 + 1026037 = 1026090
59 + 1026031 = 1026090
61 + 1026029 = 1026090
151 + 1025939 = 1026090
173 + 1025917 = 1026090

Showing the first eight; more decompositions exist.
