Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404994, here are decompositions:

  • 3 + 2147404991 = 2147404994
  • 13 + 2147404981 = 2147404994
  • 37 + 2147404957 = 2147404994
  • 61 + 2147404933 = 2147404994
  • 103 + 2147404891 = 2147404994
  • 223 + 2147404771 = 2147404994
  • 283 + 2147404711 = 2147404994
  • 373 + 2147404621 = 2147404994

Showing the first eight; more decompositions exist.
