Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11542, here are decompositions:

23 + 11519 = 11542
53 + 11489 = 11542
59 + 11483 = 11542
71 + 11471 = 11542
131 + 11411 = 11542
149 + 11393 = 11542
173 + 11369 = 11542
191 + 11351 = 11542

Showing the first eight; more decompositions exist.
