Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13208, here are decompositions:

31 + 13177 = 13208
37 + 13171 = 13208
61 + 13147 = 13208
109 + 13099 = 13208
199 + 13009 = 13208
229 + 12979 = 13208
241 + 12967 = 13208
367 + 12841 = 13208

Showing the first eight; more decompositions exist.
