Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18748, here are decompositions:

5 + 18743 = 18748
17 + 18731 = 18748
29 + 18719 = 18748
47 + 18701 = 18748
131 + 18617 = 18748
227 + 18521 = 18748
347 + 18401 = 18748
419 + 18329 = 18748

Showing the first eight; more decompositions exist.
