Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75816, here are decompositions:
- 19 + 75797 = 75816
- 23 + 75793 = 75816
- 29 + 75787 = 75816
- 43 + 75773 = 75816
- 73 + 75743 = 75816
- 107 + 75709 = 75816
- 109 + 75707 = 75816
- 113 + 75703 = 75816
Showing the first eight; more decompositions exist.
