Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497976, here are decompositions:

  • 37 + 2147497939 = 2147497976
  • 277 + 2147497699 = 2147497976
  • 313 + 2147497663 = 2147497976
  • 487 + 2147497489 = 2147497976
  • 733 + 2147497243 = 2147497976
  • 739 + 2147497237 = 2147497976
  • 937 + 2147497039 = 2147497976
  • 997 + 2147496979 = 2147497976

Showing the first eight; more decompositions exist.
