Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28944, here are decompositions:
- 11 + 28933 = 28944
- 17 + 28927 = 28944
- 23 + 28921 = 28944
- 43 + 28901 = 28944
- 73 + 28871 = 28944
- 101 + 28843 = 28944
- 107 + 28837 = 28944
- 127 + 28817 = 28944
Showing the first eight; more decompositions exist.
