Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387006, here are decompositions:
- 3 + 2147387003 = 2147387006
- 19 + 2147386987 = 2147387006
- 277 + 2147386729 = 2147387006
- 307 + 2147386699 = 2147387006
- 367 + 2147386639 = 2147387006
- 379 + 2147386627 = 2147387006
- 547 + 2147386459 = 2147387006
- 619 + 2147386387 = 2147387006
Showing the first eight; more decompositions exist.
