Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387716, here are decompositions:
- 3 + 2147387713 = 2147387716
- 17 + 2147387699 = 2147387716
- 107 + 2147387609 = 2147387716
- 503 + 2147387213 = 2147387716
- 563 + 2147387153 = 2147387716
- 653 + 2147387063 = 2147387716
- 863 + 2147386853 = 2147387716
- 983 + 2147386733 = 2147387716
Showing the first eight; more decompositions exist.
