Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387204, here are decompositions:
- 73 + 2147387131 = 2147387204
- 283 + 2147386921 = 2147387204
- 577 + 2147386627 = 2147387204
- 643 + 2147386561 = 2147387204
- 733 + 2147386471 = 2147387204
- 757 + 2147386447 = 2147387204
- 997 + 2147386207 = 2147387204
- 1087 + 2147386117 = 2147387204
Showing the first eight; more decompositions exist.
