Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64780, here are decompositions:
- 17 + 64763 = 64780
- 71 + 64709 = 64780
- 101 + 64679 = 64780
- 113 + 64667 = 64780
- 167 + 64613 = 64780
- 179 + 64601 = 64780
- 227 + 64553 = 64780
- 281 + 64499 = 64780
Showing the first eight; more decompositions exist.
