Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147446882, here are decompositions:
- 11 + 2147446871 = 2147446882
- 41 + 2147446841 = 2147446882
- 89 + 2147446793 = 2147446882
- 263 + 2147446619 = 2147446882
- 311 + 2147446571 = 2147446882
- 443 + 2147446439 = 2147446882
- 491 + 2147446391 = 2147446882
- 509 + 2147446373 = 2147446882
Showing the first eight; more decompositions exist.
