Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29920, here are decompositions:
- 3 + 29917 = 29920
- 41 + 29879 = 29920
- 47 + 29873 = 29920
- 53 + 29867 = 29920
- 83 + 29837 = 29920
- 101 + 29819 = 29920
- 131 + 29789 = 29920
- 167 + 29753 = 29920
Showing the first eight; more decompositions exist.
