Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28948, here are decompositions:
- 47 + 28901 = 28948
- 89 + 28859 = 28948
- 131 + 28817 = 28948
- 197 + 28751 = 28948
- 251 + 28697 = 28948
- 317 + 28631 = 28948
- 389 + 28559 = 28948
- 401 + 28547 = 28948
Showing the first eight; more decompositions exist.
