Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57648, here are decompositions:
- 7 + 57641 = 57648
- 11 + 57637 = 57648
- 47 + 57601 = 57648
- 61 + 57587 = 57648
- 89 + 57559 = 57648
- 181 + 57467 = 57648
- 191 + 57457 = 57648
- 251 + 57397 = 57648
Showing the first eight; more decompositions exist.
