Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497904, here are decompositions:

  • 3 + 2147497901 = 2147497904
  • 241 + 2147497663 = 2147497904
  • 397 + 2147497507 = 2147497904
  • 457 + 2147497447 = 2147497904
  • 661 + 2147497243 = 2147497904
  • 823 + 2147497081 = 2147497904
  • 907 + 2147496997 = 2147497904
  • 967 + 2147496937 = 2147497904

Showing the first eight; more decompositions exist.
