Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482942, here are decompositions:
- 5 + 2147482937 = 2147482942
- 83 + 2147482859 = 2147482942
- 131 + 2147482811 = 2147482942
- 179 + 2147482763 = 2147482942
- 281 + 2147482661 = 2147482942
- 359 + 2147482583 = 2147482942
- 461 + 2147482481 = 2147482942
- 593 + 2147482349 = 2147482942
Showing the first eight; more decompositions exist.
