Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13418, here are decompositions:

7 + 13411 = 13418
19 + 13399 = 13418
37 + 13381 = 13418
79 + 13339 = 13418
109 + 13309 = 13418
127 + 13291 = 13418
151 + 13267 = 13418
199 + 13219 = 13418

Showing the first eight; more decompositions exist.
