Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21322, here are decompositions:
- 3 + 21319 = 21322
- 5 + 21317 = 21322
- 53 + 21269 = 21322
- 101 + 21221 = 21322
- 131 + 21191 = 21322
- 173 + 21149 = 21322
- 179 + 21143 = 21322
- 233 + 21089 = 21322
Showing the first eight; more decompositions exist.
