Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028310, here are decompositions:

7 + 1028303 = 1028310
37 + 1028273 = 1028310
47 + 1028263 = 1028310
67 + 1028243 = 1028310
79 + 1028231 = 1028310
89 + 1028221 = 1028310
97 + 1028213 = 1028310
103 + 1028207 = 1028310

Showing the first eight; more decompositions exist.
