Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17868, here are decompositions:
- 5 + 17863 = 17868
- 17 + 17851 = 17868
- 29 + 17839 = 17868
- 31 + 17837 = 17868
- 41 + 17827 = 17868
- 61 + 17807 = 17868
- 79 + 17789 = 17868
- 107 + 17761 = 17868
Showing the first eight; more decompositions exist.
