Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75720, here are decompositions:

11 + 75709 = 75720
13 + 75707 = 75720
17 + 75703 = 75720
31 + 75689 = 75720
37 + 75683 = 75720
41 + 75679 = 75720
61 + 75659 = 75720
67 + 75653 = 75720

Showing the first eight; more decompositions exist.
