Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21326, here are decompositions:

3 + 21323 = 21326
7 + 21319 = 21326
13 + 21313 = 21326
43 + 21283 = 21326
79 + 21247 = 21326
139 + 21187 = 21326
157 + 21169 = 21326
163 + 21163 = 21326

Showing the first eight; more decompositions exist.
