Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387446, here are decompositions:
- 5 + 2147387441 = 2147387446
- 53 + 2147387393 = 2147387446
- 107 + 2147387339 = 2147387446
- 167 + 2147387279 = 2147387446
- 227 + 2147387219 = 2147387446
- 233 + 2147387213 = 2147387446
- 293 + 2147387153 = 2147387446
- 383 + 2147387063 = 2147387446
Showing the first eight; more decompositions exist.
