Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387482, here are decompositions:
- 41 + 2147387441 = 2147387482
- 89 + 2147387393 = 2147387482
- 263 + 2147387219 = 2147387482
- 269 + 2147387213 = 2147387482
- 419 + 2147387063 = 2147387482
- 479 + 2147387003 = 2147387482
- 599 + 2147386883 = 2147387482
- 881 + 2147386601 = 2147387482
Showing the first eight; more decompositions exist.
