Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1032720, here are decompositions:

11 + 1032709 = 1032720
19 + 1032701 = 1032720
23 + 1032697 = 1032720
37 + 1032683 = 1032720
41 + 1032679 = 1032720
71 + 1032649 = 1032720
103 + 1032617 = 1032720
107 + 1032613 = 1032720

Showing the first eight; more decompositions exist.
