Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497694, here are decompositions:

  • 3 + 2147497691 = 2147497694
  • 31 + 2147497663 = 2147497694
  • 283 + 2147497411 = 2147497694
  • 373 + 2147497321 = 2147497694
  • 457 + 2147497237 = 2147497694
  • 613 + 2147497081 = 2147497694
  • 733 + 2147496961 = 2147497694
  • 757 + 2147496937 = 2147497694

Showing the first eight; more decompositions exist.
