Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147547008, here are decompositions:

  • 7 + 2147547001 = 2147547008
  • 31 + 2147546977 = 2147547008
  • 97 + 2147546911 = 2147547008
  • 127 + 2147546881 = 2147547008
  • 157 + 2147546851 = 2147547008
  • 241 + 2147546767 = 2147547008
  • 337 + 2147546671 = 2147547008
  • 379 + 2147546629 = 2147547008

Showing the first eight; more decompositions exist.
