Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21176, here are decompositions:

7 + 21169 = 21176
13 + 21163 = 21176
19 + 21157 = 21176
37 + 21139 = 21176
109 + 21067 = 21176
157 + 21019 = 21176
163 + 21013 = 21176
193 + 20983 = 21176

Showing the first eight; more decompositions exist.
