Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23686, here are decompositions:
- 17 + 23669 = 23686
- 23 + 23663 = 23686
- 53 + 23633 = 23686
- 59 + 23627 = 23686
- 83 + 23603 = 23686
- 137 + 23549 = 23686
- 149 + 23537 = 23686
- 227 + 23459 = 23686
Showing the first eight; more decompositions exist.
