Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498452, here are decompositions:

  • 3 + 2147498449 = 2147498452
  • 53 + 2147498399 = 2147498452
  • 59 + 2147498393 = 2147498452
  • 89 + 2147498363 = 2147498452
  • 173 + 2147498279 = 2147498452
  • 263 + 2147498189 = 2147498452
  • 311 + 2147498141 = 2147498452
  • 419 + 2147498033 = 2147498452

Showing the first eight; more decompositions exist.
