Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482678, here are decompositions:
- 17 + 2147482661 = 2147482678
- 101 + 2147482577 = 2147482678
- 197 + 2147482481 = 2147482678
- 269 + 2147482409 = 2147482678
- 311 + 2147482367 = 2147482678
- 317 + 2147482361 = 2147482678
- 557 + 2147482121 = 2147482678
- 587 + 2147482091 = 2147482678
Showing the first eight; more decompositions exist.
