Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135906, here are decompositions:
- 7 + 135899 = 135906
- 13 + 135893 = 135906
- 19 + 135887 = 135906
- 47 + 135859 = 135906
- 107 + 135799 = 135906
- 149 + 135757 = 135906
- 163 + 135743 = 135906
- 179 + 135727 = 135906
Showing the first eight; more decompositions exist.
