Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188154, here are decompositions:

7 + 188147 = 188154
11 + 188143 = 188154
17 + 188137 = 188154
47 + 188107 = 188154
137 + 188017 = 188154
167 + 187987 = 188154
181 + 187973 = 188154
191 + 187963 = 188154

Showing the first eight; more decompositions exist.
