Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79920, here are decompositions:
- 13 + 79907 = 79920
- 17 + 79903 = 79920
- 19 + 79901 = 79920
- 31 + 79889 = 79920
- 47 + 79873 = 79920
- 53 + 79867 = 79920
- 59 + 79861 = 79920
- 73 + 79847 = 79920
Showing the first eight; more decompositions exist.
