Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57538, here are decompositions:
- 11 + 57527 = 57538
- 71 + 57467 = 57538
- 149 + 57389 = 57538
- 191 + 57347 = 57538
- 251 + 57287 = 57538
- 269 + 57269 = 57538
- 317 + 57221 = 57538
- 347 + 57191 = 57538
Showing the first eight; more decompositions exist.
