Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468992, here are decompositions:

  • 5 + 2147468987 = 2147468992
  • 59 + 2147468933 = 2147468992
  • 83 + 2147468909 = 2147468992
  • 131 + 2147468861 = 2147468992
  • 191 + 2147468801 = 2147468992
  • 239 + 2147468753 = 2147468992
  • 353 + 2147468639 = 2147468992
  • 401 + 2147468591 = 2147468992

Showing the first eight; more decompositions exist.
