Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24858, here are decompositions:

7 + 24851 = 24858
11 + 24847 = 24858
17 + 24841 = 24858
37 + 24821 = 24858
59 + 24799 = 24858
109 + 24749 = 24858
149 + 24709 = 24858
167 + 24691 = 24858

Showing the first eight; more decompositions exist.
