Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497718, here are decompositions:

  • 19 + 2147497699 = 2147497718
  • 211 + 2147497507 = 2147497718
  • 229 + 2147497489 = 2147497718
  • 271 + 2147497447 = 2147497718
  • 307 + 2147497411 = 2147497718
  • 397 + 2147497321 = 2147497718
  • 577 + 2147497141 = 2147497718
  • 739 + 2147496979 = 2147497718

Showing the first eight; more decompositions exist.
