Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122644, here are decompositions:
- 47 + 122597 = 122644
- 83 + 122561 = 122644
- 167 + 122477 = 122644
- 173 + 122471 = 122644
- 191 + 122453 = 122644
- 251 + 122393 = 122644
- 257 + 122387 = 122644
- 281 + 122363 = 122644
Showing the first eight; more decompositions exist.
