Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497256, here are decompositions:

  • 13 + 2147497243 = 2147497256
  • 19 + 2147497237 = 2147497256
  • 277 + 2147496979 = 2147497256
  • 397 + 2147496859 = 2147497256
  • 409 + 2147496847 = 2147497256
  • 439 + 2147496817 = 2147497256
  • 523 + 2147496733 = 2147497256
  • 739 + 2147496517 = 2147497256

Showing the first eight; more decompositions exist.
