Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482672, here are decompositions:
- 11 + 2147482661 = 2147482672
- 89 + 2147482583 = 2147482672
- 191 + 2147482481 = 2147482672
- 263 + 2147482409 = 2147482672
- 311 + 2147482361 = 2147482672
- 449 + 2147482223 = 2147482672
- 773 + 2147481899 = 2147482672
- 809 + 2147481863 = 2147482672
Showing the first eight; more decompositions exist.
