Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71920, here are decompositions:
- 3 + 71917 = 71920
- 11 + 71909 = 71920
- 41 + 71879 = 71920
- 53 + 71867 = 71920
- 59 + 71861 = 71920
- 71 + 71849 = 71920
- 83 + 71837 = 71920
- 113 + 71807 = 71920
Showing the first eight; more decompositions exist.
