Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147541722, here are decompositions:

  • 19 + 2147541703 = 2147541722
  • 31 + 2147541691 = 2147541722
  • 163 + 2147541559 = 2147541722
  • 331 + 2147541391 = 2147541722
  • 349 + 2147541373 = 2147541722
  • 409 + 2147541313 = 2147541722
  • 439 + 2147541283 = 2147541722
  • 541 + 2147541181 = 2147541722

Showing the first eight; more decompositions exist.
