Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482668, here are decompositions:
- 5 + 2147482663 = 2147482668
- 7 + 2147482661 = 2147482668
- 47 + 2147482621 = 2147482668
- 167 + 2147482501 = 2147482668
- 251 + 2147482417 = 2147482668
- 307 + 2147482361 = 2147482668
- 431 + 2147482237 = 2147482668
- 547 + 2147482121 = 2147482668
Showing the first eight; more decompositions exist.
