Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17372, here are decompositions:
- 13 + 17359 = 17372
- 31 + 17341 = 17372
- 73 + 17299 = 17372
- 79 + 17293 = 17372
- 163 + 17209 = 17372
- 181 + 17191 = 17372
- 331 + 17041 = 17372
- 379 + 16993 = 17372
Showing the first eight; more decompositions exist.
