Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147551814, here are decompositions:

  • 3 + 2147551811 = 2147551814
  • 13 + 2147551801 = 2147551814
  • 181 + 2147551633 = 2147551814
  • 223 + 2147551591 = 2147551814
  • 307 + 2147551507 = 2147551814
  • 997 + 2147550817 = 2147551814
  • 1117 + 2147550697 = 2147551814
  • 1231 + 2147550583 = 2147551814

Showing the first eight; more decompositions exist.
