Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68620, here are decompositions:
- 23 + 68597 = 68620
- 53 + 68567 = 68620
- 89 + 68531 = 68620
- 113 + 68507 = 68620
- 131 + 68489 = 68620
- 137 + 68483 = 68620
- 173 + 68447 = 68620
- 269 + 68351 = 68620
Showing the first eight; more decompositions exist.
