Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047720, here are decompositions:

7 + 1047713 = 1047720
17 + 1047703 = 1047720
19 + 1047701 = 1047720
29 + 1047691 = 1047720
31 + 1047689 = 1047720
53 + 1047667 = 1047720
67 + 1047653 = 1047720
71 + 1047649 = 1047720

Showing the first eight; more decompositions exist.
