Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24800, here are decompositions:

7 + 24793 = 24800
19 + 24781 = 24800
37 + 24763 = 24800
67 + 24733 = 24800
103 + 24697 = 24800
109 + 24691 = 24800
229 + 24571 = 24800
283 + 24517 = 24800

Showing the first eight; more decompositions exist.
