Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498518, here are decompositions:

  • 17 + 2147498501 = 2147498518
  • 47 + 2147498471 = 2147498518
  • 131 + 2147498387 = 2147498518
  • 239 + 2147498279 = 2147498518
  • 401 + 2147498117 = 2147498518
  • 569 + 2147497949 = 2147498518
  • 617 + 2147497901 = 2147498518
  • 761 + 2147497757 = 2147498518

Showing the first eight; more decompositions exist.
