Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387318, here are decompositions:
- 19 + 2147387299 = 2147387318
- 61 + 2147387257 = 2147387318
- 331 + 2147386987 = 2147387318
- 397 + 2147386921 = 2147387318
- 607 + 2147386711 = 2147387318
- 619 + 2147386699 = 2147387318
- 631 + 2147386687 = 2147387318
- 691 + 2147386627 = 2147387318
Showing the first eight; more decompositions exist.
