Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13158, here are decompositions:

7 + 13151 = 13158
11 + 13147 = 13158
31 + 13127 = 13158
37 + 13121 = 13158
59 + 13099 = 13158
109 + 13049 = 13158
149 + 13009 = 13158
151 + 13007 = 13158

Showing the first eight; more decompositions exist.
