Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135568, here are decompositions:
- 71 + 135497 = 135568
- 89 + 135479 = 135568
- 101 + 135467 = 135568
- 107 + 135461 = 135568
- 137 + 135431 = 135568
- 179 + 135389 = 135568
- 239 + 135329 = 135568
- 311 + 135257 = 135568
Showing the first eight; more decompositions exist.
