Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12758, here are decompositions:

19 + 12739 = 12758
37 + 12721 = 12758
61 + 12697 = 12758
139 + 12619 = 12758
157 + 12601 = 12758
181 + 12577 = 12758
211 + 12547 = 12758
241 + 12517 = 12758

Showing the first eight; more decompositions exist.
