Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028312, here are decompositions:

3 + 1028309 = 1028312
163 + 1028149 = 1028312
199 + 1028113 = 1028312
211 + 1028101 = 1028312
223 + 1028089 = 1028312
283 + 1028029 = 1028312
421 + 1027891 = 1028312
619 + 1027693 = 1028312

Showing the first eight; more decompositions exist.
