Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047730, here are decompositions:

17 + 1047713 = 1047730
29 + 1047701 = 1047730
41 + 1047689 = 1047730
59 + 1047671 = 1047730
83 + 1047647 = 1047730
179 + 1047551 = 1047730
191 + 1047539 = 1047730
197 + 1047533 = 1047730

Showing the first eight; more decompositions exist.
