Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497480, here are decompositions:

  • 131 + 2147497349 = 2147497480
  • 347 + 2147497133 = 2147497480
  • 461 + 2147497019 = 2147497480
  • 509 + 2147496971 = 2147497480
  • 563 + 2147496917 = 2147497480
  • 617 + 2147496863 = 2147497480
  • 641 + 2147496839 = 2147497480
  • 701 + 2147496779 = 2147497480

Showing the first eight; more decompositions exist.
