Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11508, here are decompositions:

5 + 11503 = 11508
11 + 11497 = 11508
17 + 11491 = 11508
19 + 11489 = 11508
37 + 11471 = 11508
41 + 11467 = 11508
61 + 11447 = 11508
71 + 11437 = 11508

Showing the first eight; more decompositions exist.
