Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11512, here are decompositions:

23 + 11489 = 11512
29 + 11483 = 11512
41 + 11471 = 11512
89 + 11423 = 11512
101 + 11411 = 11512
113 + 11399 = 11512
191 + 11321 = 11512
233 + 11279 = 11512

Showing the first eight; more decompositions exist.
