Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12788, here are decompositions:

7 + 12781 = 12788
31 + 12757 = 12788
67 + 12721 = 12788
151 + 12637 = 12788
199 + 12589 = 12788
211 + 12577 = 12788
241 + 12547 = 12788
271 + 12517 = 12788

Showing the first eight; more decompositions exist.
