Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169358, here are decompositions:
- 19 + 169339 = 169358
- 31 + 169327 = 169358
- 37 + 169321 = 169358
- 109 + 169249 = 169358
- 139 + 169219 = 169358
- 181 + 169177 = 169358
- 199 + 169159 = 169358
- 229 + 169129 = 169358
Showing the first eight; more decompositions exist.
