Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11894, here are decompositions:
- 7 + 11887 = 11894
- 31 + 11863 = 11894
- 61 + 11833 = 11894
- 67 + 11827 = 11894
- 73 + 11821 = 11894
- 151 + 11743 = 11894
- 163 + 11731 = 11894
- 193 + 11701 = 11894
Showing the first eight; more decompositions exist.
