Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147552018, here are decompositions:

  • 19 + 2147551999 = 2147552018
  • 67 + 2147551951 = 2147552018
  • 151 + 2147551867 = 2147552018
  • 631 + 2147551387 = 2147552018
  • 757 + 2147551261 = 2147552018
  • 769 + 2147551249 = 2147552018
  • 1051 + 2147550967 = 2147552018
  • 1117 + 2147550901 = 2147552018

Showing the first eight; more decompositions exist.
