Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67864, here are decompositions:
- 11 + 67853 = 67864
- 101 + 67763 = 67864
- 107 + 67757 = 67864
- 113 + 67751 = 67864
- 131 + 67733 = 67864
- 233 + 67631 = 67864
- 257 + 67607 = 67864
- 263 + 67601 = 67864
Showing the first eight; more decompositions exist.
