Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047742, here are decompositions:

5 + 1047737 = 1047742
29 + 1047713 = 1047742
41 + 1047701 = 1047742
53 + 1047689 = 1047742
71 + 1047671 = 1047742
89 + 1047653 = 1047742
191 + 1047551 = 1047742
251 + 1047491 = 1047742

Showing the first eight; more decompositions exist.
