Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28636, here are decompositions:
- 5 + 28631 = 28636
- 17 + 28619 = 28636
- 29 + 28607 = 28636
- 89 + 28547 = 28636
- 137 + 28499 = 28636
- 173 + 28463 = 28636
- 197 + 28439 = 28636
- 227 + 28409 = 28636
Showing the first eight; more decompositions exist.
