Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11406, here are decompositions:

7 + 11399 = 11406
13 + 11393 = 11406
23 + 11383 = 11406
37 + 11369 = 11406
53 + 11353 = 11406
89 + 11317 = 11406
107 + 11299 = 11406
127 + 11279 = 11406

Showing the first eight; more decompositions exist.
