Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028306, here are decompositions:

3 + 1028303 = 1028306
43 + 1028263 = 1028306
157 + 1028149 = 1028306
193 + 1028113 = 1028306
199 + 1028107 = 1028306
277 + 1028029 = 1028306
283 + 1028023 = 1028306
337 + 1027969 = 1028306

Showing the first eight; more decompositions exist.
