Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513270, here are decompositions:
- 11 + 31513259 = 31513270
- 83 + 31513187 = 31513270
- 179 + 31513091 = 31513270
- 197 + 31513073 = 31513270
- 233 + 31513037 = 31513270
- 263 + 31513007 = 31513270
- 311 + 31512959 = 31513270
- 401 + 31512869 = 31513270
Showing the first eight; more decompositions exist.
