Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136840, here are decompositions:
- 29 + 136811 = 136840
- 71 + 136769 = 136840
- 89 + 136751 = 136840
- 101 + 136739 = 136840
- 107 + 136733 = 136840
- 113 + 136727 = 136840
- 131 + 136709 = 136840
- 149 + 136691 = 136840
Showing the first eight; more decompositions exist.
