Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21192, here are decompositions:

5 + 21187 = 21192
13 + 21179 = 21192
23 + 21169 = 21192
29 + 21163 = 21192
43 + 21149 = 21192
53 + 21139 = 21192
71 + 21121 = 21192
103 + 21089 = 21192

Showing the first eight; more decompositions exist.
