Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452, here are decompositions:
- 59 + 31393 = 31452
- 61 + 31391 = 31452
- 73 + 31379 = 31452
- 131 + 31321 = 31452
- 181 + 31271 = 31452
- 193 + 31259 = 31452
- 199 + 31253 = 31452
- 229 + 31223 = 31452
Showing the first eight; more decompositions exist.
