Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18754, here are decompositions:

5 + 18749 = 18754
11 + 18743 = 18754
23 + 18731 = 18754
41 + 18713 = 18754
53 + 18701 = 18754
83 + 18671 = 18754
137 + 18617 = 18754
167 + 18587 = 18754

Showing the first eight; more decompositions exist.
