Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387896, here are decompositions:
- 167 + 2147387729 = 2147387896
- 197 + 2147387699 = 2147387896
- 389 + 2147387507 = 2147387896
- 503 + 2147387393 = 2147387896
- 557 + 2147387339 = 2147387896
- 617 + 2147387279 = 2147387896
- 677 + 2147387219 = 2147387896
- 683 + 2147387213 = 2147387896
Showing the first eight; more decompositions exist.
