Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002556, here are decompositions:

3 + 1002553 = 1002556
29 + 1002527 = 1002556
53 + 1002503 = 1002556
89 + 1002467 = 1002556
179 + 1002377 = 1002556
197 + 1002359 = 1002556
257 + 1002299 = 1002556
293 + 1002263 = 1002556

Showing the first eight; more decompositions exist.
