Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162238, here are decompositions:
- 17 + 162221 = 162238
- 29 + 162209 = 162238
- 179 + 162059 = 162238
- 227 + 162011 = 162238
- 239 + 161999 = 162238
- 269 + 161969 = 162238
- 281 + 161957 = 162238
- 317 + 161921 = 162238
Showing the first eight; more decompositions exist.
