Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28224, here are decompositions:
- 5 + 28219 = 28224
- 13 + 28211 = 28224
- 23 + 28201 = 28224
- 41 + 28183 = 28224
- 43 + 28181 = 28224
- 61 + 28163 = 28224
- 73 + 28151 = 28224
- 101 + 28123 = 28224
Showing the first eight; more decompositions exist.
