Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021546, here are decompositions:

5 + 1021541 = 1021546
59 + 1021487 = 1021546
83 + 1021463 = 1021546
89 + 1021457 = 1021546
173 + 1021373 = 1021546
179 + 1021367 = 1021546
257 + 1021289 = 1021546
263 + 1021283 = 1021546

Showing the first eight; more decompositions exist.
