Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482694, here are decompositions:
- 13 + 2147482681 = 2147482694
- 31 + 2147482663 = 2147482694
- 73 + 2147482621 = 2147482694
- 103 + 2147482591 = 2147482694
- 193 + 2147482501 = 2147482694
- 277 + 2147482417 = 2147482694
- 367 + 2147482327 = 2147482694
- 421 + 2147482273 = 2147482694
Showing the first eight; more decompositions exist.
