Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387158, here are decompositions:
- 5 + 2147387153 = 2147387158
- 149 + 2147387009 = 2147387158
- 401 + 2147386757 = 2147387158
- 431 + 2147386727 = 2147387158
- 491 + 2147386667 = 2147387158
- 557 + 2147386601 = 2147387158
- 881 + 2147386277 = 2147387158
- 887 + 2147386271 = 2147387158
Showing the first eight; more decompositions exist.
