Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387384, here are decompositions:
- 61 + 2147387323 = 2147387384
- 127 + 2147387257 = 2147387384
- 157 + 2147387227 = 2147387384
- 367 + 2147387017 = 2147387384
- 397 + 2147386987 = 2147387384
- 463 + 2147386921 = 2147387384
- 631 + 2147386753 = 2147387384
- 673 + 2147386711 = 2147387384
Showing the first eight; more decompositions exist.
