Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28030, here are decompositions:
- 3 + 28027 = 28030
- 11 + 28019 = 28030
- 29 + 28001 = 28030
- 47 + 27983 = 28030
- 83 + 27947 = 28030
- 89 + 27941 = 28030
- 113 + 27917 = 28030
- 137 + 27893 = 28030
Showing the first eight; more decompositions exist.
