Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126208, here are decompositions:
- 101 + 126107 = 126208
- 167 + 126041 = 126208
- 197 + 126011 = 126208
- 281 + 125927 = 126208
- 311 + 125897 = 126208
- 419 + 125789 = 126208
- 431 + 125777 = 126208
- 491 + 125717 = 126208
Showing the first eight; more decompositions exist.
