Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028268, here are decompositions:

5 + 1028263 = 1028268
37 + 1028231 = 1028268
47 + 1028221 = 1028268
61 + 1028207 = 1028268
67 + 1028201 = 1028268
79 + 1028189 = 1028268
127 + 1028141 = 1028268
139 + 1028129 = 1028268

Showing the first eight; more decompositions exist.
