Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23542, here are decompositions:

3 + 23539 = 23542
5 + 23537 = 23542
11 + 23531 = 23542
83 + 23459 = 23542
173 + 23369 = 23542
251 + 23291 = 23542
263 + 23279 = 23542
353 + 23189 = 23542

Showing the first eight; more decompositions exist.
