Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028646, here are decompositions:

29 + 1028617 = 1028646
67 + 1028579 = 1028646
89 + 1028557 = 1028646
137 + 1028509 = 1028646
167 + 1028479 = 1028646
173 + 1028473 = 1028646
257 + 1028389 = 1028646
313 + 1028333 = 1028646

Showing the first eight; more decompositions exist.
