Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387150, here are decompositions:
- 19 + 2147387131 = 2147387150
- 67 + 2147387083 = 2147387150
- 163 + 2147386987 = 2147387150
- 229 + 2147386921 = 2147387150
- 397 + 2147386753 = 2147387150
- 421 + 2147386729 = 2147387150
- 439 + 2147386711 = 2147387150
- 463 + 2147386687 = 2147387150
Showing the first eight; more decompositions exist.
