Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71988, here are decompositions:
- 5 + 71983 = 71988
- 17 + 71971 = 71988
- 41 + 71947 = 71988
- 47 + 71941 = 71988
- 71 + 71917 = 71988
- 79 + 71909 = 71988
- 89 + 71899 = 71988
- 101 + 71887 = 71988
Showing the first eight; more decompositions exist.
