Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97800, here are decompositions:
- 11 + 97789 = 97800
- 13 + 97787 = 97800
- 23 + 97777 = 97800
- 29 + 97771 = 97800
- 71 + 97729 = 97800
- 89 + 97711 = 97800
- 113 + 97687 = 97800
- 127 + 97673 = 97800
Showing the first eight; more decompositions exist.
