Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30874, here are decompositions:
- 3 + 30871 = 30874
- 5 + 30869 = 30874
- 23 + 30851 = 30874
- 71 + 30803 = 30874
- 101 + 30773 = 30874
- 167 + 30707 = 30874
- 197 + 30677 = 30874
- 281 + 30593 = 30874
Showing the first eight; more decompositions exist.
