Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23550, here are decompositions:

11 + 23539 = 23550
13 + 23537 = 23550
19 + 23531 = 23550
41 + 23509 = 23550
53 + 23497 = 23550
103 + 23447 = 23550
151 + 23399 = 23550
179 + 23371 = 23550

Showing the first eight; more decompositions exist.
