Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21334, here are decompositions:
- 11 + 21323 = 21334
- 17 + 21317 = 21334
- 107 + 21227 = 21334
- 113 + 21221 = 21334
- 191 + 21143 = 21334
- 227 + 21107 = 21334
- 233 + 21101 = 21334
- 311 + 21023 = 21334
Showing the first eight; more decompositions exist.
