Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147550458, here are decompositions:

  • 37 + 2147550421 = 2147550458
  • 271 + 2147550187 = 2147550458
  • 307 + 2147550151 = 2147550458
  • 331 + 2147550127 = 2147550458
  • 337 + 2147550121 = 2147550458
  • 601 + 2147549857 = 2147550458
  • 619 + 2147549839 = 2147550458
  • 631 + 2147549827 = 2147550458

Showing the first eight; more decompositions exist.
