Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147377874, here are decompositions:
- 3 + 2147377871 = 2147377874
- 241 + 2147377633 = 2147377874
- 283 + 2147377591 = 2147377874
- 307 + 2147377567 = 2147377874
- 601 + 2147377273 = 2147377874
- 643 + 2147377231 = 2147377874
- 661 + 2147377213 = 2147377874
- 991 + 2147376883 = 2147377874
Showing the first eight; more decompositions exist.
