Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57542, here are decompositions:
- 13 + 57529 = 57542
- 193 + 57349 = 57542
- 211 + 57331 = 57542
- 241 + 57301 = 57542
- 271 + 57271 = 57542
- 283 + 57259 = 57542
- 349 + 57193 = 57542
- 379 + 57163 = 57542
Showing the first eight; more decompositions exist.
