Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483278, here are decompositions:
- 29 + 2147483249 = 2147483278
- 41 + 2147483237 = 2147483278
- 107 + 2147483171 = 2147483278
- 401 + 2147482877 = 2147483278
- 419 + 2147482859 = 2147483278
- 461 + 2147482817 = 2147483278
- 467 + 2147482811 = 2147483278
- 617 + 2147482661 = 2147483278
Showing the first eight; more decompositions exist.
