Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137158, here are decompositions:
- 5 + 137153 = 137158
- 11 + 137147 = 137158
- 41 + 137117 = 137158
- 71 + 137087 = 137158
- 167 + 136991 = 137158
- 179 + 136979 = 137158
- 269 + 136889 = 137158
- 317 + 136841 = 137158
Showing the first eight; more decompositions exist.
