Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158256, here are decompositions:
- 13 + 158243 = 158256
- 23 + 158233 = 158256
- 29 + 158227 = 158256
- 47 + 158209 = 158256
- 67 + 158189 = 158256
- 113 + 158143 = 158256
- 127 + 158129 = 158256
- 179 + 158077 = 158256
Showing the first eight; more decompositions exist.
