Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498458, here are decompositions:

  • 59 + 2147498399 = 2147498458
  • 71 + 2147498387 = 2147498458
  • 179 + 2147498279 = 2147498458
  • 269 + 2147498189 = 2147498458
  • 311 + 2147498147 = 2147498458
  • 317 + 2147498141 = 2147498458
  • 509 + 2147497949 = 2147498458
  • 557 + 2147497901 = 2147498458

Showing the first eight; more decompositions exist.
