Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387024, here are decompositions:
- 7 + 2147387017 = 2147387024
- 37 + 2147386987 = 2147387024
- 103 + 2147386921 = 2147387024
- 271 + 2147386753 = 2147387024
- 313 + 2147386711 = 2147387024
- 337 + 2147386687 = 2147387024
- 397 + 2147386627 = 2147387024
- 463 + 2147386561 = 2147387024
Showing the first eight; more decompositions exist.
