Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499484, here are decompositions:

  • 3 + 2147499481 = 2147499484
  • 5 + 2147499479 = 2147499484
  • 23 + 2147499461 = 2147499484
  • 47 + 2147499437 = 2147499484
  • 71 + 2147499413 = 2147499484
  • 83 + 2147499401 = 2147499484
  • 173 + 2147499311 = 2147499484
  • 191 + 2147499293 = 2147499484

Showing the first eight; more decompositions exist.
