Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31432, here are decompositions:
- 41 + 31391 = 31432
- 53 + 31379 = 31432
- 113 + 31319 = 31432
- 173 + 31259 = 31432
- 179 + 31253 = 31432
- 239 + 31193 = 31432
- 251 + 31181 = 31432
- 281 + 31151 = 31432
Showing the first eight; more decompositions exist.
