Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174840, here are decompositions:
- 11 + 174829 = 174840
- 19 + 174821 = 174840
- 41 + 174799 = 174840
- 67 + 174773 = 174840
- 73 + 174767 = 174840
- 79 + 174761 = 174840
- 103 + 174737 = 174840
- 137 + 174703 = 174840
Showing the first eight; more decompositions exist.
