Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75864, here are decompositions:
- 11 + 75853 = 75864
- 31 + 75833 = 75864
- 43 + 75821 = 75864
- 67 + 75797 = 75864
- 71 + 75793 = 75864
- 83 + 75781 = 75864
- 97 + 75767 = 75864
- 157 + 75707 = 75864
Showing the first eight; more decompositions exist.
