Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18724, here are decompositions:

5 + 18719 = 18724
11 + 18713 = 18724
23 + 18701 = 18724
53 + 18671 = 18724
107 + 18617 = 18724
131 + 18593 = 18724
137 + 18587 = 18724
263 + 18461 = 18724

Showing the first eight; more decompositions exist.
