Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78906, here are decompositions:
- 5 + 78901 = 78906
- 13 + 78893 = 78906
- 17 + 78889 = 78906
- 19 + 78887 = 78906
- 29 + 78877 = 78906
- 53 + 78853 = 78906
- 67 + 78839 = 78906
- 83 + 78823 = 78906
Showing the first eight; more decompositions exist.
