Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147582902, here are decompositions:

  • 29 + 2147582873 = 2147582902
  • 41 + 2147582861 = 2147582902
  • 131 + 2147582771 = 2147582902
  • 239 + 2147582663 = 2147582902
  • 281 + 2147582621 = 2147582902
  • 359 + 2147582543 = 2147582902
  • 503 + 2147582399 = 2147582902
  • 599 + 2147582303 = 2147582902

Showing the first eight; more decompositions exist.
