Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21410, here are decompositions:

3 + 21407 = 21410
13 + 21397 = 21410
19 + 21391 = 21410
31 + 21379 = 21410
97 + 21313 = 21410
127 + 21283 = 21410
163 + 21247 = 21410
199 + 21211 = 21410

Showing the first eight; more decompositions exist.
