Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387484, here are decompositions:
- 43 + 2147387441 = 2147387484
- 71 + 2147387413 = 2147387484
- 101 + 2147387383 = 2147387484
- 227 + 2147387257 = 2147387484
- 257 + 2147387227 = 2147387484
- 271 + 2147387213 = 2147387484
- 331 + 2147387153 = 2147387484
- 353 + 2147387131 = 2147387484
Showing the first eight; more decompositions exist.
