Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23428, here are decompositions:

11 + 23417 = 23428
29 + 23399 = 23428
59 + 23369 = 23428
71 + 23357 = 23428
89 + 23339 = 23428
101 + 23327 = 23428
107 + 23321 = 23428
131 + 23297 = 23428

Showing the first eight; more decompositions exist.
