Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42238, here are decompositions:
- 11 + 42227 = 42238
- 17 + 42221 = 42238
- 29 + 42209 = 42238
- 41 + 42197 = 42238
- 59 + 42179 = 42238
- 107 + 42131 = 42238
- 137 + 42101 = 42238
- 149 + 42089 = 42238
Showing the first eight; more decompositions exist.
