Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163658, here are decompositions:
- 31 + 163627 = 163658
- 37 + 163621 = 163658
- 97 + 163561 = 163658
- 181 + 163477 = 163658
- 241 + 163417 = 163658
- 307 + 163351 = 163658
- 331 + 163327 = 163658
- 337 + 163321 = 163658
Showing the first eight; more decompositions exist.
