Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163946, here are decompositions:
- 19 + 163927 = 163946
- 37 + 163909 = 163946
- 127 + 163819 = 163946
- 157 + 163789 = 163946
- 193 + 163753 = 163946
- 313 + 163633 = 163946
- 373 + 163573 = 163946
- 379 + 163567 = 163946
Showing the first eight; more decompositions exist.
