Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11550, here are decompositions:

23 + 11527 = 11550
31 + 11519 = 11550
47 + 11503 = 11550
53 + 11497 = 11550
59 + 11491 = 11550
61 + 11489 = 11550
67 + 11483 = 11550
79 + 11471 = 11550

Showing the first eight; more decompositions exist.
