Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147433970, here are decompositions:
- 23 + 2147433947 = 2147433970
- 41 + 2147433929 = 2147433970
- 83 + 2147433887 = 2147433970
- 179 + 2147433791 = 2147433970
- 191 + 2147433779 = 2147433970
- 251 + 2147433719 = 2147433970
- 263 + 2147433707 = 2147433970
- 419 + 2147433551 = 2147433970
Showing the first eight; more decompositions exist.
