Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57242, here are decompositions:
- 19 + 57223 = 57242
- 79 + 57163 = 57242
- 103 + 57139 = 57242
- 313 + 56929 = 57242
- 331 + 56911 = 57242
- 349 + 56893 = 57242
- 421 + 56821 = 57242
- 433 + 56809 = 57242
Showing the first eight; more decompositions exist.
