Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28048, here are decompositions:
- 17 + 28031 = 28048
- 29 + 28019 = 28048
- 47 + 28001 = 28048
- 101 + 27947 = 28048
- 107 + 27941 = 28048
- 131 + 27917 = 28048
- 197 + 27851 = 28048
- 239 + 27809 = 28048
Showing the first eight; more decompositions exist.
