Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6778, here are decompositions:
- 17 + 6761 = 6778
- 41 + 6737 = 6778
- 59 + 6719 = 6778
- 89 + 6689 = 6778
- 179 + 6599 = 6778
- 197 + 6581 = 6778
- 227 + 6551 = 6778
- 257 + 6521 = 6778
Showing the first eight; more decompositions exist.
