Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147377258, here are decompositions:
- 11 + 2147377247 = 2147377258
- 17 + 2147377241 = 2147377258
- 239 + 2147377019 = 2147377258
- 269 + 2147376989 = 2147377258
- 641 + 2147376617 = 2147377258
- 701 + 2147376557 = 2147377258
- 839 + 2147376419 = 2147377258
- 857 + 2147376401 = 2147377258
Showing the first eight; more decompositions exist.
