Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497244, here are decompositions:

  • 7 + 2147497237 = 2147497244
  • 43 + 2147497201 = 2147497244
  • 103 + 2147497141 = 2147497244
  • 163 + 2147497081 = 2147497244
  • 283 + 2147496961 = 2147497244
  • 307 + 2147496937 = 2147497244
  • 397 + 2147496847 = 2147497244
  • 727 + 2147496517 = 2147497244

Showing the first eight; more decompositions exist.
