Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97778, here are decompositions:
- 7 + 97771 = 97778
- 67 + 97711 = 97778
- 127 + 97651 = 97778
- 199 + 97579 = 97778
- 229 + 97549 = 97778
- 277 + 97501 = 97778
- 337 + 97441 = 97778
- 349 + 97429 = 97778
Showing the first eight; more decompositions exist.
