Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79880, here are decompositions:
- 7 + 79873 = 79880
- 13 + 79867 = 79880
- 19 + 79861 = 79880
- 37 + 79843 = 79880
- 67 + 79813 = 79880
- 79 + 79801 = 79880
- 103 + 79777 = 79880
- 181 + 79699 = 79880
Showing the first eight; more decompositions exist.
