Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470194, here are decompositions:
- 43 + 31470151 = 31470194
- 97 + 31470097 = 31470194
- 127 + 31470067 = 31470194
- 157 + 31470037 = 31470194
- 181 + 31470013 = 31470194
- 241 + 31469953 = 31470194
- 271 + 31469923 = 31470194
- 337 + 31469857 = 31470194
Showing the first eight; more decompositions exist.
