Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029742, here are decompositions:

11 + 1029731 = 1029742
53 + 1029689 = 1029742
89 + 1029653 = 1029742
149 + 1029593 = 1029742
173 + 1029569 = 1029742
179 + 1029563 = 1029742
269 + 1029473 = 1029742
359 + 1029383 = 1029742

Showing the first eight; more decompositions exist.
