Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28958, here are decompositions:
- 31 + 28927 = 28958
- 37 + 28921 = 28958
- 79 + 28879 = 28958
- 151 + 28807 = 28958
- 199 + 28759 = 28958
- 229 + 28729 = 28958
- 271 + 28687 = 28958
- 331 + 28627 = 28958
Showing the first eight; more decompositions exist.
