Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21362, here are decompositions:
- 43 + 21319 = 21362
- 79 + 21283 = 21362
- 151 + 21211 = 21362
- 193 + 21169 = 21362
- 199 + 21163 = 21362
- 223 + 21139 = 21362
- 241 + 21121 = 21362
- 331 + 21031 = 21362
Showing the first eight; more decompositions exist.
