Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028750, here are decompositions:

3 + 1028747 = 1028750
13 + 1028737 = 1028750
67 + 1028683 = 1028750
103 + 1028647 = 1028750
181 + 1028569 = 1028750
193 + 1028557 = 1028750
241 + 1028509 = 1028750
271 + 1028479 = 1028750

Showing the first eight; more decompositions exist.
