Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57822, here are decompositions:

13 + 57809 = 57822
19 + 57803 = 57822
29 + 57793 = 57822
31 + 57791 = 57822
41 + 57781 = 57822
71 + 57751 = 57822
103 + 57719 = 57822
109 + 57713 = 57822

Showing the first eight; more decompositions exist.
