Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158306, here are decompositions:
- 3 + 158303 = 158306
- 13 + 158293 = 158306
- 37 + 158269 = 158306
- 73 + 158233 = 158306
- 79 + 158227 = 158306
- 97 + 158209 = 158306
- 163 + 158143 = 158306
- 193 + 158113 = 158306
Showing the first eight; more decompositions exist.
