Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147546818, here are decompositions:

  • 5 + 2147546813 = 2147546818
  • 71 + 2147546747 = 2147546818
  • 191 + 2147546627 = 2147546818
  • 257 + 2147546561 = 2147546818
  • 569 + 2147546249 = 2147546818
  • 617 + 2147546201 = 2147546818
  • 797 + 2147546021 = 2147546818
  • 827 + 2147545991 = 2147546818

Showing the first eight; more decompositions exist.
