Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42686, here are decompositions:
- 3 + 42683 = 42686
- 19 + 42667 = 42686
- 37 + 42649 = 42686
- 43 + 42643 = 42686
- 97 + 42589 = 42686
- 109 + 42577 = 42686
- 199 + 42487 = 42686
- 223 + 42463 = 42686
Showing the first eight; more decompositions exist.
