Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174870, here are decompositions:
- 11 + 174859 = 174870
- 19 + 174851 = 174870
- 41 + 174829 = 174870
- 71 + 174799 = 174870
- 97 + 174773 = 174870
- 103 + 174767 = 174870
- 107 + 174763 = 174870
- 109 + 174761 = 174870
Showing the first eight; more decompositions exist.
