Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387262, here are decompositions:
- 5 + 2147387257 = 2147387262
- 43 + 2147387219 = 2147387262
- 109 + 2147387153 = 2147387262
- 131 + 2147387131 = 2147387262
- 179 + 2147387083 = 2147387262
- 199 + 2147387063 = 2147387262
- 233 + 2147387029 = 2147387262
- 379 + 2147386883 = 2147387262
Showing the first eight; more decompositions exist.
