Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133906, here are decompositions:
- 29 + 133877 = 133906
- 53 + 133853 = 133906
- 137 + 133769 = 133906
- 173 + 133733 = 133906
- 197 + 133709 = 133906
- 233 + 133673 = 133906
- 257 + 133649 = 133906
- 347 + 133559 = 133906
Showing the first eight; more decompositions exist.
