Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158182, here are decompositions:
- 41 + 158141 = 158182
- 53 + 158129 = 158182
- 173 + 158009 = 158182
- 179 + 158003 = 158182
- 191 + 157991 = 158182
- 251 + 157931 = 158182
- 281 + 157901 = 158182
- 293 + 157889 = 158182
Showing the first eight; more decompositions exist.
