Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387822, here are decompositions:
- 31 + 2147387791 = 2147387822
- 79 + 2147387743 = 2147387822
- 103 + 2147387719 = 2147387822
- 109 + 2147387713 = 2147387822
- 193 + 2147387629 = 2147387822
- 409 + 2147387413 = 2147387822
- 439 + 2147387383 = 2147387822
- 499 + 2147387323 = 2147387822
Showing the first eight; more decompositions exist.
