Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387288, here are decompositions:
- 31 + 2147387257 = 2147387288
- 61 + 2147387227 = 2147387288
- 157 + 2147387131 = 2147387288
- 229 + 2147387059 = 2147387288
- 271 + 2147387017 = 2147387288
- 367 + 2147386921 = 2147387288
- 577 + 2147386711 = 2147387288
- 601 + 2147386687 = 2147387288
Showing the first eight; more decompositions exist.
