Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38158, here are decompositions:
- 5 + 38153 = 38158
- 89 + 38069 = 38158
- 167 + 37991 = 38158
- 191 + 37967 = 38158
- 251 + 37907 = 38158
- 269 + 37889 = 38158
- 311 + 37847 = 38158
- 347 + 37811 = 38158
Showing the first eight; more decompositions exist.
