Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23578, here are decompositions:

11 + 23567 = 23578
17 + 23561 = 23578
29 + 23549 = 23578
41 + 23537 = 23578
47 + 23531 = 23578
131 + 23447 = 23578
179 + 23399 = 23578
239 + 23339 = 23578

Showing the first eight; more decompositions exist.
