Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147585006, here are decompositions:

  • 139 + 2147584867 = 2147585006
  • 199 + 2147584807 = 2147585006
  • 313 + 2147584693 = 2147585006
  • 337 + 2147584669 = 2147585006
  • 349 + 2147584657 = 2147585006
  • 397 + 2147584609 = 2147585006
  • 409 + 2147584597 = 2147585006
  • 487 + 2147584519 = 2147585006

Showing the first eight; more decompositions exist.
