Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147384572, here are decompositions:

  • 71 + 2147384501 = 2147384572
  • 239 + 2147384333 = 2147384572
  • 461 + 2147384111 = 2147384572
  • 569 + 2147384003 = 2147384572
  • 701 + 2147383871 = 2147384572
  • 743 + 2147383829 = 2147384572
  • 863 + 2147383709 = 2147384572
  • 1091 + 2147383481 = 2147384572

Showing the first eight; more decompositions exist.
