Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158164, here are decompositions:
- 3 + 158161 = 158164
- 23 + 158141 = 158164
- 173 + 157991 = 158164
- 233 + 157931 = 158164
- 257 + 157907 = 158164
- 263 + 157901 = 158164
- 431 + 157733 = 158164
- 443 + 157721 = 158164
Showing the first eight; more decompositions exist.
