Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584744, here are decompositions:

  • 47 + 2147584697 = 2147584744
  • 83 + 2147584661 = 2147584744
  • 191 + 2147584553 = 2147584744
  • 353 + 2147584391 = 2147584744
  • 401 + 2147584343 = 2147584744
  • 467 + 2147584277 = 2147584744
  • 491 + 2147584253 = 2147584744
  • 563 + 2147584181 = 2147584744

Showing the first eight; more decompositions exist.
