Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13154, here are decompositions:

3 + 13151 = 13154
7 + 13147 = 13154
61 + 13093 = 13154
151 + 13003 = 13154
181 + 12973 = 13154
313 + 12841 = 13154
331 + 12823 = 13154
373 + 12781 = 13154

Showing the first eight; more decompositions exist.
