Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17898, here are decompositions:
- 7 + 17891 = 17898
- 17 + 17881 = 17898
- 47 + 17851 = 17898
- 59 + 17839 = 17898
- 61 + 17837 = 17898
- 71 + 17827 = 17898
- 107 + 17791 = 17898
- 109 + 17789 = 17898
Showing the first eight; more decompositions exist.
