Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11388, here are decompositions:

5 + 11383 = 11388
19 + 11369 = 11388
37 + 11351 = 11388
59 + 11329 = 11388
67 + 11321 = 11388
71 + 11317 = 11388
89 + 11299 = 11388
101 + 11287 = 11388

Showing the first eight; more decompositions exist.
