Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24390, here are decompositions:

11 + 24379 = 24390
17 + 24373 = 24390
19 + 24371 = 24390
31 + 24359 = 24390
53 + 24337 = 24390
61 + 24329 = 24390
73 + 24317 = 24390
109 + 24281 = 24390

Showing the first eight; more decompositions exist.
