Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468938, here are decompositions:

  • 5 + 2147468933 = 2147468938
  • 29 + 2147468909 = 2147468938
  • 137 + 2147468801 = 2147468938
  • 317 + 2147468621 = 2147468938
  • 347 + 2147468591 = 2147468938
  • 401 + 2147468537 = 2147468938
  • 431 + 2147468507 = 2147468938
  • 509 + 2147468429 = 2147468938

Showing the first eight; more decompositions exist.
