Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163646, here are decompositions:
- 3 + 163643 = 163646
- 13 + 163633 = 163646
- 19 + 163627 = 163646
- 73 + 163573 = 163646
- 79 + 163567 = 163646
- 103 + 163543 = 163646
- 163 + 163483 = 163646
- 229 + 163417 = 163646
Showing the first eight; more decompositions exist.
