Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21482, here are decompositions:
- 103 + 21379 = 21482
- 163 + 21319 = 21482
- 199 + 21283 = 21482
- 271 + 21211 = 21482
- 313 + 21169 = 21482
- 421 + 21061 = 21482
- 463 + 21019 = 21482
- 499 + 20983 = 21482
Showing the first eight; more decompositions exist.
