Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57742, here are decompositions:

5 + 57737 = 57742
11 + 57731 = 57742
23 + 57719 = 57742
29 + 57713 = 57742
53 + 57689 = 57742
89 + 57653 = 57742
101 + 57641 = 57742
149 + 57593 = 57742

Showing the first eight; more decompositions exist.
