Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11398, here are decompositions:

5 + 11393 = 11398
29 + 11369 = 11398
47 + 11351 = 11398
137 + 11261 = 11398
227 + 11171 = 11398
239 + 11159 = 11398
281 + 11117 = 11398
311 + 11087 = 11398

Showing the first eight; more decompositions exist.
