Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387404, here are decompositions:
- 11 + 2147387393 = 2147387404
- 191 + 2147387213 = 2147387404
- 251 + 2147387153 = 2147387404
- 401 + 2147387003 = 2147387404
- 521 + 2147386883 = 2147387404
- 647 + 2147386757 = 2147387404
- 677 + 2147386727 = 2147387404
- 797 + 2147386607 = 2147387404
Showing the first eight; more decompositions exist.
