Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28850, here are decompositions:
- 7 + 28843 = 28850
- 13 + 28837 = 28850
- 37 + 28813 = 28850
- 43 + 28807 = 28850
- 61 + 28789 = 28850
- 79 + 28771 = 28850
- 97 + 28753 = 28850
- 127 + 28723 = 28850
Showing the first eight; more decompositions exist.
