Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163802, here are decompositions:
- 13 + 163789 = 163802
- 31 + 163771 = 163802
- 61 + 163741 = 163802
- 73 + 163729 = 163802
- 181 + 163621 = 163802
- 229 + 163573 = 163802
- 241 + 163561 = 163802
- 409 + 163393 = 163802
Showing the first eight; more decompositions exist.
