Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97820, here are decompositions:
- 7 + 97813 = 97820
- 31 + 97789 = 97820
- 43 + 97777 = 97820
- 109 + 97711 = 97820
- 211 + 97609 = 97820
- 241 + 97579 = 97820
- 271 + 97549 = 97820
- 367 + 97453 = 97820
Showing the first eight; more decompositions exist.
