Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498564, here are decompositions:

  • 151 + 2147498413 = 2147498564
  • 223 + 2147498341 = 2147498564
  • 487 + 2147498077 = 2147498564
  • 643 + 2147497921 = 2147498564
  • 1117 + 2147497447 = 2147498564
  • 1153 + 2147497411 = 2147498564
  • 1171 + 2147497393 = 2147498564
  • 1321 + 2147497243 = 2147498564

Showing the first eight; more decompositions exist.
