Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130268, here are decompositions:

7 + 130261 = 130268
67 + 130201 = 130268
97 + 130171 = 130268
181 + 130087 = 130268
199 + 130069 = 130268
211 + 130057 = 130268
241 + 130027 = 130268
331 + 129937 = 130268

Showing the first eight; more decompositions exist.
