Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607170, here are decompositions:
- 17 + 31607153 = 31607170
- 83 + 31607087 = 31607170
- 131 + 31607039 = 31607170
- 173 + 31606997 = 31607170
- 191 + 31606979 = 31607170
- 197 + 31606973 = 31607170
- 227 + 31606943 = 31607170
- 239 + 31606931 = 31607170
Showing the first eight; more decompositions exist.
