Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028636, here are decompositions:

19 + 1028617 = 1028636
67 + 1028569 = 1028636
79 + 1028557 = 1028636
127 + 1028509 = 1028636
157 + 1028479 = 1028636
163 + 1028473 = 1028636
199 + 1028437 = 1028636
307 + 1028329 = 1028636

Showing the first eight; more decompositions exist.
