Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482944, here are decompositions:
- 7 + 2147482937 = 2147482944
- 23 + 2147482921 = 2147482944
- 67 + 2147482877 = 2147482944
- 71 + 2147482873 = 2147482944
- 127 + 2147482817 = 2147482944
- 181 + 2147482763 = 2147482944
- 251 + 2147482693 = 2147482944
- 263 + 2147482681 = 2147482944
Showing the first eight; more decompositions exist.
