Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147585008, here are decompositions:

  • 11 + 2147584997 = 2147585008
  • 59 + 2147584949 = 2147585008
  • 137 + 2147584871 = 2147585008
  • 197 + 2147584811 = 2147585008
  • 227 + 2147584781 = 2147585008
  • 311 + 2147584697 = 2147585008
  • 347 + 2147584661 = 2147585008
  • 479 + 2147584529 = 2147585008

Showing the first eight; more decompositions exist.
