Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24840, here are decompositions:

19 + 24821 = 24840
31 + 24809 = 24840
41 + 24799 = 24840
47 + 24793 = 24840
59 + 24781 = 24840
73 + 24767 = 24840
107 + 24733 = 24840
131 + 24709 = 24840

Showing the first eight; more decompositions exist.
