Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498238, here are decompositions:

  • 29 + 2147498209 = 2147498238
  • 59 + 2147498179 = 2147498238
  • 97 + 2147498141 = 2147498238
  • 317 + 2147497921 = 2147498238
  • 331 + 2147497907 = 2147498238
  • 337 + 2147497901 = 2147498238
  • 349 + 2147497889 = 2147498238
  • 467 + 2147497771 = 2147498238

Showing the first eight; more decompositions exist.
