Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21336, here are decompositions:
- 13 + 21323 = 21336
- 17 + 21319 = 21336
- 19 + 21317 = 21336
- 23 + 21313 = 21336
- 53 + 21283 = 21336
- 59 + 21277 = 21336
- 67 + 21269 = 21336
- 89 + 21247 = 21336
Showing the first eight; more decompositions exist.
