Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497646, here are decompositions:

  • 139 + 2147497507 = 2147497646
  • 157 + 2147497489 = 2147497646
  • 199 + 2147497447 = 2147497646
  • 409 + 2147497237 = 2147497646
  • 607 + 2147497039 = 2147497646
  • 709 + 2147496937 = 2147497646
  • 787 + 2147496859 = 2147497646
  • 829 + 2147496817 = 2147497646

Showing the first eight; more decompositions exist.
