Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028260, here are decompositions:

17 + 1028243 = 1028260
29 + 1028231 = 1028260
47 + 1028213 = 1028260
53 + 1028207 = 1028260
59 + 1028201 = 1028260
71 + 1028189 = 1028260
131 + 1028129 = 1028260
179 + 1028081 = 1028260

Showing the first eight; more decompositions exist.
