Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79900, here are decompositions:
- 11 + 79889 = 79900
- 53 + 79847 = 79900
- 59 + 79841 = 79900
- 71 + 79829 = 79900
- 83 + 79817 = 79900
- 89 + 79811 = 79900
- 131 + 79769 = 79900
- 269 + 79631 = 79900
Showing the first eight; more decompositions exist.
