Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488836, here are decompositions:

  • 43 + 2147488793 = 2147488836
  • 109 + 2147488727 = 2147488836
  • 193 + 2147488643 = 2147488836
  • 223 + 2147488613 = 2147488836
  • 257 + 2147488579 = 2147488836
  • 263 + 2147488573 = 2147488836
  • 277 + 2147488559 = 2147488836
  • 293 + 2147488543 = 2147488836

Showing the first eight; more decompositions exist.
