Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387084, here are decompositions:
- 67 + 2147387017 = 2147387084
- 97 + 2147386987 = 2147387084
- 163 + 2147386921 = 2147387084
- 331 + 2147386753 = 2147387084
- 373 + 2147386711 = 2147387084
- 397 + 2147386687 = 2147387084
- 457 + 2147386627 = 2147387084
- 523 + 2147386561 = 2147387084
Showing the first eight; more decompositions exist.
