Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18718, here are decompositions:

5 + 18713 = 18718
17 + 18701 = 18718
47 + 18671 = 18718
101 + 18617 = 18718
131 + 18587 = 18718
179 + 18539 = 18718
197 + 18521 = 18718
257 + 18461 = 18718

Showing the first eight; more decompositions exist.
