Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57388, here are decompositions:
- 5 + 57383 = 57388
- 41 + 57347 = 57388
- 59 + 57329 = 57388
- 101 + 57287 = 57388
- 137 + 57251 = 57388
- 167 + 57221 = 57388
- 197 + 57191 = 57388
- 239 + 57149 = 57388
Showing the first eight; more decompositions exist.
