Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70878, here are decompositions:
- 11 + 70867 = 70878
- 29 + 70849 = 70878
- 37 + 70841 = 70878
- 109 + 70769 = 70878
- 149 + 70729 = 70878
- 191 + 70687 = 70878
- 211 + 70667 = 70878
- 239 + 70639 = 70878
Showing the first eight; more decompositions exist.
