Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130256, here are decompositions:

3 + 130253 = 130256
73 + 130183 = 130256
109 + 130147 = 130256
157 + 130099 = 130256
199 + 130057 = 130256
229 + 130027 = 130256
337 + 129919 = 130256
463 + 129793 = 130256

Showing the first eight; more decompositions exist.
