Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57840, here are decompositions:
- 11 + 57829 = 57840
- 31 + 57809 = 57840
- 37 + 57803 = 57840
- 47 + 57793 = 57840
- 53 + 57787 = 57840
- 59 + 57781 = 57840
- 67 + 57773 = 57840
- 89 + 57751 = 57840
Showing the first eight; more decompositions exist.
