Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133158, here are decompositions:
- 5 + 133153 = 133158
- 37 + 133121 = 133158
- 41 + 133117 = 133158
- 61 + 133097 = 133158
- 71 + 133087 = 133158
- 89 + 133069 = 133158
- 107 + 133051 = 133158
- 191 + 132967 = 133158
Showing the first eight; more decompositions exist.
