Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584918, here are decompositions:

  • 47 + 2147584871 = 2147584918
  • 71 + 2147584847 = 2147584918
  • 107 + 2147584811 = 2147584918
  • 137 + 2147584781 = 2147584918
  • 239 + 2147584679 = 2147584918
  • 257 + 2147584661 = 2147584918
  • 389 + 2147584529 = 2147584918
  • 461 + 2147584457 = 2147584918

Showing the first eight; more decompositions exist.
