Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163156, here are decompositions:
- 5 + 163151 = 163156
- 29 + 163127 = 163156
- 47 + 163109 = 163156
- 137 + 163019 = 163156
- 167 + 162989 = 163156
- 239 + 162917 = 163156
- 317 + 162839 = 163156
- 443 + 162713 = 163156
Showing the first eight; more decompositions exist.
