Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387704, here are decompositions:
- 5 + 2147387699 = 2147387704
- 53 + 2147387651 = 2147387704
- 131 + 2147387573 = 2147387704
- 173 + 2147387531 = 2147387704
- 197 + 2147387507 = 2147387704
- 263 + 2147387441 = 2147387704
- 311 + 2147387393 = 2147387704
- 491 + 2147387213 = 2147387704
Showing the first eight; more decompositions exist.
