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.
