Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57838, here are decompositions:

29 + 57809 = 57838
47 + 57791 = 57838
101 + 57737 = 57838
107 + 57731 = 57838
149 + 57689 = 57838
197 + 57641 = 57838
251 + 57587 = 57838
281 + 57557 = 57838

Showing the first eight; more decompositions exist.
