Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24780, here are decompositions:

13 + 24767 = 24780
17 + 24763 = 24780
31 + 24749 = 24780
47 + 24733 = 24780
71 + 24709 = 24780
83 + 24697 = 24780
89 + 24691 = 24780
97 + 24683 = 24780

Showing the first eight; more decompositions exist.
