Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11408, here are decompositions:

79 + 11329 = 11408
97 + 11311 = 11408
109 + 11299 = 11408
151 + 11257 = 11408
157 + 11251 = 11408
211 + 11197 = 11408
277 + 11131 = 11408
337 + 11071 = 11408

Showing the first eight; more decompositions exist.
