Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029420, here are decompositions:

11 + 1029409 = 1029420
13 + 1029407 = 1029420
17 + 1029403 = 1029420
37 + 1029383 = 1029420
59 + 1029361 = 1029420
61 + 1029359 = 1029420
71 + 1029349 = 1029420
79 + 1029341 = 1029420

Showing the first eight; more decompositions exist.
