Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021338, here are decompositions:

5 + 1021333 = 1021338
7 + 1021331 = 1021338
11 + 1021327 = 1021338
37 + 1021301 = 1021338
41 + 1021297 = 1021338
47 + 1021291 = 1021338
67 + 1021271 = 1021338
79 + 1021259 = 1021338

Showing the first eight; more decompositions exist.
