Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21332, here are decompositions:
- 13 + 21319 = 21332
- 19 + 21313 = 21332
- 139 + 21193 = 21332
- 163 + 21169 = 21332
- 193 + 21139 = 21332
- 211 + 21121 = 21332
- 271 + 21061 = 21332
- 313 + 21019 = 21332
Showing the first eight; more decompositions exist.
