Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70990, here are decompositions:
- 11 + 70979 = 70990
- 41 + 70949 = 70990
- 53 + 70937 = 70990
- 71 + 70919 = 70990
- 89 + 70901 = 70990
- 113 + 70877 = 70990
- 137 + 70853 = 70990
- 149 + 70841 = 70990
Showing the first eight; more decompositions exist.
