Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57840, here are decompositions:

11 + 57829 = 57840
31 + 57809 = 57840
37 + 57803 = 57840
47 + 57793 = 57840
53 + 57787 = 57840
59 + 57781 = 57840
67 + 57773 = 57840
89 + 57751 = 57840

Showing the first eight; more decompositions exist.
