Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162436, here are decompositions:
- 17 + 162419 = 162436
- 23 + 162413 = 162436
- 47 + 162389 = 162436
- 149 + 162287 = 162436
- 167 + 162269 = 162436
- 173 + 162263 = 162436
- 179 + 162257 = 162436
- 227 + 162209 = 162436
Showing the first eight; more decompositions exist.
