Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469920, here are decompositions:

  • 3 + 2147469917 = 2147469920
  • 97 + 2147469823 = 2147469920
  • 103 + 2147469817 = 2147469920
  • 139 + 2147469781 = 2147469920
  • 241 + 2147469679 = 2147469920
  • 283 + 2147469637 = 2147469920
  • 367 + 2147469553 = 2147469920
  • 457 + 2147469463 = 2147469920

Showing the first eight; more decompositions exist.
