Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136648, here are decompositions:
- 41 + 136607 = 136648
- 47 + 136601 = 136648
- 89 + 136559 = 136648
- 101 + 136547 = 136648
- 107 + 136541 = 136648
- 137 + 136511 = 136648
- 167 + 136481 = 136648
- 227 + 136421 = 136648
Showing the first eight; more decompositions exist.
