Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10578, here are decompositions:
- 11 + 10567 = 10578
- 19 + 10559 = 10578
- 47 + 10531 = 10578
- 79 + 10499 = 10578
- 101 + 10477 = 10578
- 149 + 10429 = 10578
- 151 + 10427 = 10578
- 179 + 10399 = 10578
Showing the first eight; more decompositions exist.
