Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13466, here are decompositions:

3 + 13463 = 13466
67 + 13399 = 13466
127 + 13339 = 13466
139 + 13327 = 13466
157 + 13309 = 13466
199 + 13267 = 13466
283 + 13183 = 13466
307 + 13159 = 13466

Showing the first eight; more decompositions exist.
