Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387260, here are decompositions:
- 3 + 2147387257 = 2147387260
- 41 + 2147387219 = 2147387260
- 47 + 2147387213 = 2147387260
- 107 + 2147387153 = 2147387260
- 197 + 2147387063 = 2147387260
- 251 + 2147387009 = 2147387260
- 257 + 2147387003 = 2147387260
- 503 + 2147386757 = 2147387260
Showing the first eight; more decompositions exist.
