Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17854, here are decompositions:

3 + 17851 = 17854
17 + 17837 = 17854
47 + 17807 = 17854
71 + 17783 = 17854
107 + 17747 = 17854
173 + 17681 = 17854
197 + 17657 = 17854
227 + 17627 = 17854

Showing the first eight; more decompositions exist.
