Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163668, here are decompositions:
- 7 + 163661 = 163668
- 31 + 163637 = 163668
- 41 + 163627 = 163668
- 47 + 163621 = 163668
- 67 + 163601 = 163668
- 101 + 163567 = 163668
- 107 + 163561 = 163668
- 151 + 163517 = 163668
Showing the first eight; more decompositions exist.
