Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28536, here are decompositions:
- 19 + 28517 = 28536
- 23 + 28513 = 28536
- 37 + 28499 = 28536
- 43 + 28493 = 28536
- 59 + 28477 = 28536
- 73 + 28463 = 28536
- 89 + 28447 = 28536
- 97 + 28439 = 28536
Showing the first eight; more decompositions exist.
