Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488938, here are decompositions:

  • 19 + 2147488919 = 2147488938
  • 31 + 2147488907 = 2147488938
  • 71 + 2147488867 = 2147488938
  • 79 + 2147488859 = 2147488938
  • 197 + 2147488741 = 2147488938
  • 211 + 2147488727 = 2147488938
  • 359 + 2147488579 = 2147488938
  • 379 + 2147488559 = 2147488938

Showing the first eight; more decompositions exist.
