Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158194, here are decompositions:
- 5 + 158189 = 158194
- 53 + 158141 = 158194
- 191 + 158003 = 158194
- 263 + 157931 = 158194
- 293 + 157901 = 158194
- 317 + 157877 = 158194
- 353 + 157841 = 158194
- 401 + 157793 = 158194
Showing the first eight; more decompositions exist.
