Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105238, here are decompositions:
- 11 + 105227 = 105238
- 71 + 105167 = 105238
- 101 + 105137 = 105238
- 131 + 105107 = 105238
- 167 + 105071 = 105238
- 239 + 104999 = 105238
- 251 + 104987 = 105238
- 347 + 104891 = 105238
Showing the first eight; more decompositions exist.
