Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500828, here are decompositions:

  • 47 + 2147500781 = 2147500828
  • 131 + 2147500697 = 2147500828
  • 167 + 2147500661 = 2147500828
  • 269 + 2147500559 = 2147500828
  • 467 + 2147500361 = 2147500828
  • 569 + 2147500259 = 2147500828
  • 587 + 2147500241 = 2147500828
  • 701 + 2147500127 = 2147500828

Showing the first eight; more decompositions exist.
