Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21326, here are decompositions:
- 3 + 21323 = 21326
- 7 + 21319 = 21326
- 13 + 21313 = 21326
- 43 + 21283 = 21326
- 79 + 21247 = 21326
- 139 + 21187 = 21326
- 157 + 21169 = 21326
- 163 + 21163 = 21326
Showing the first eight; more decompositions exist.
