Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75726, here are decompositions:

5 + 75721 = 75726
17 + 75709 = 75726
19 + 75707 = 75726
23 + 75703 = 75726
37 + 75689 = 75726
43 + 75683 = 75726
47 + 75679 = 75726
67 + 75659 = 75726

Showing the first eight; more decompositions exist.
