Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021446, here are decompositions:

5 + 1021441 = 1021446
17 + 1021429 = 1021446
29 + 1021417 = 1021446
43 + 1021403 = 1021446
59 + 1021387 = 1021446
73 + 1021373 = 1021446
79 + 1021367 = 1021446
113 + 1021333 = 1021446

Showing the first eight; more decompositions exist.
