Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171824, here are decompositions:
- 13 + 171811 = 171824
- 31 + 171793 = 171824
- 61 + 171763 = 171824
- 67 + 171757 = 171824
- 127 + 171697 = 171824
- 151 + 171673 = 171824
- 241 + 171583 = 171824
- 271 + 171553 = 171824
Showing the first eight; more decompositions exist.
