Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425658, here are decompositions:

  • 67 + 2147425591 = 2147425658
  • 127 + 2147425531 = 2147425658
  • 139 + 2147425519 = 2147425658
  • 151 + 2147425507 = 2147425658
  • 211 + 2147425447 = 2147425658
  • 277 + 2147425381 = 2147425658
  • 349 + 2147425309 = 2147425658
  • 409 + 2147425249 = 2147425658

Showing the first eight; more decompositions exist.
