Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57442, here are decompositions:
- 29 + 57413 = 57442
- 53 + 57389 = 57442
- 59 + 57383 = 57442
- 113 + 57329 = 57442
- 173 + 57269 = 57442
- 191 + 57251 = 57442
- 239 + 57203 = 57442
- 251 + 57191 = 57442
Showing the first eight; more decompositions exist.
