Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136656, here are decompositions:
- 5 + 136651 = 136656
- 7 + 136649 = 136656
- 53 + 136603 = 136656
- 83 + 136573 = 136656
- 97 + 136559 = 136656
- 109 + 136547 = 136656
- 137 + 136519 = 136656
- 173 + 136483 = 136656
Showing the first eight; more decompositions exist.
