Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97780, here are decompositions:
- 3 + 97777 = 97780
- 107 + 97673 = 97780
- 131 + 97649 = 97780
- 167 + 97613 = 97780
- 173 + 97607 = 97780
- 197 + 97583 = 97780
- 227 + 97553 = 97780
- 233 + 97547 = 97780
Showing the first eight; more decompositions exist.
