Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163898, here are decompositions:
- 37 + 163861 = 163898
- 79 + 163819 = 163898
- 109 + 163789 = 163898
- 127 + 163771 = 163898
- 157 + 163741 = 163898
- 271 + 163627 = 163898
- 277 + 163621 = 163898
- 331 + 163567 = 163898
Showing the first eight; more decompositions exist.
