Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42620, here are decompositions:
- 31 + 42589 = 42620
- 43 + 42577 = 42620
- 157 + 42463 = 42620
- 163 + 42457 = 42620
- 211 + 42409 = 42620
- 223 + 42397 = 42620
- 229 + 42391 = 42620
- 241 + 42379 = 42620
Showing the first eight; more decompositions exist.
