Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13158, here are decompositions:
- 7 + 13151 = 13158
- 11 + 13147 = 13158
- 31 + 13127 = 13158
- 37 + 13121 = 13158
- 59 + 13099 = 13158
- 109 + 13049 = 13158
- 149 + 13009 = 13158
- 151 + 13007 = 13158
Showing the first eight; more decompositions exist.
