Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136528, here are decompositions:
- 5 + 136523 = 136528
- 17 + 136511 = 136528
- 47 + 136481 = 136528
- 107 + 136421 = 136528
- 131 + 136397 = 136528
- 149 + 136379 = 136528
- 167 + 136361 = 136528
- 191 + 136337 = 136528
Showing the first eight; more decompositions exist.
