Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170072, here are decompositions:
- 43 + 170029 = 170072
- 139 + 169933 = 170072
- 163 + 169909 = 170072
- 181 + 169891 = 170072
- 229 + 169843 = 170072
- 241 + 169831 = 170072
- 283 + 169789 = 170072
- 379 + 169693 = 170072
Showing the first eight; more decompositions exist.
