Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147472636, here are decompositions:

  • 19 + 2147472617 = 2147472636
  • 79 + 2147472557 = 2147472636
  • 137 + 2147472499 = 2147472636
  • 167 + 2147472469 = 2147472636
  • 193 + 2147472443 = 2147472636
  • 223 + 2147472413 = 2147472636
  • 263 + 2147472373 = 2147472636
  • 293 + 2147472343 = 2147472636

Showing the first eight; more decompositions exist.
