Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13126, here are decompositions:

5 + 13121 = 13126
17 + 13109 = 13126
23 + 13103 = 13126
83 + 13043 = 13126
89 + 13037 = 13126
167 + 12959 = 13126
173 + 12953 = 13126
227 + 12899 = 13126

Showing the first eight; more decompositions exist.
