Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387460, here are decompositions:
- 19 + 2147387441 = 2147387460
- 47 + 2147387413 = 2147387460
- 67 + 2147387393 = 2147387460
- 137 + 2147387323 = 2147387460
- 181 + 2147387279 = 2147387460
- 233 + 2147387227 = 2147387460
- 241 + 2147387219 = 2147387460
- 307 + 2147387153 = 2147387460
Showing the first eight; more decompositions exist.
