Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136866, here are decompositions:
- 5 + 136861 = 136866
- 7 + 136859 = 136866
- 17 + 136849 = 136866
- 53 + 136813 = 136866
- 89 + 136777 = 136866
- 97 + 136769 = 136866
- 113 + 136753 = 136866
- 127 + 136739 = 136866
Showing the first eight; more decompositions exist.
