Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472662, here are decompositions:

  • 3 + 2147472659 = 2147472662
  • 61 + 2147472601 = 2147472662
  • 163 + 2147472499 = 2147472662
  • 193 + 2147472469 = 2147472662
  • 241 + 2147472421 = 2147472662
  • 373 + 2147472289 = 2147472662
  • 463 + 2147472199 = 2147472662
  • 571 + 2147472091 = 2147472662

Showing the first eight; more decompositions exist.
