Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57816, here are decompositions:
- 7 + 57809 = 57816
- 13 + 57803 = 57816
- 23 + 57793 = 57816
- 29 + 57787 = 57816
- 43 + 57773 = 57816
- 79 + 57737 = 57816
- 89 + 57727 = 57816
- 97 + 57719 = 57816
Showing the first eight; more decompositions exist.
