Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9154, here are decompositions:

3 + 9151 = 9154
17 + 9137 = 9154
113 + 9041 = 9154
191 + 8963 = 9154
293 + 8861 = 9154
317 + 8837 = 9154
347 + 8807 = 9154
401 + 8753 = 9154

Showing the first eight; more decompositions exist.
