Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147435998, here are decompositions:
- 11 + 2147435987 = 2147435998
- 41 + 2147435957 = 2147435998
- 47 + 2147435951 = 2147435998
- 101 + 2147435897 = 2147435998
- 107 + 2147435891 = 2147435998
- 137 + 2147435861 = 2147435998
- 677 + 2147435321 = 2147435998
- 797 + 2147435201 = 2147435998
Showing the first eight; more decompositions exist.
