Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185854, here are decompositions:

5 + 185849 = 185854
23 + 185831 = 185854
41 + 185813 = 185854
101 + 185753 = 185854
107 + 185747 = 185854
131 + 185723 = 185854
173 + 185681 = 185854
233 + 185621 = 185854

Showing the first eight; more decompositions exist.
