Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57888, here are decompositions:
- 7 + 57881 = 57888
- 29 + 57859 = 57888
- 41 + 57847 = 57888
- 59 + 57829 = 57888
- 79 + 57809 = 57888
- 97 + 57791 = 57888
- 101 + 57787 = 57888
- 107 + 57781 = 57888
Showing the first eight; more decompositions exist.
