Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026660, here are decompositions:

67 + 1026593 = 1026660
73 + 1026587 = 1026660
79 + 1026581 = 1026660
83 + 1026577 = 1026660
97 + 1026563 = 1026660
113 + 1026547 = 1026660
139 + 1026521 = 1026660
179 + 1026481 = 1026660

Showing the first eight; more decompositions exist.
