Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497474, here are decompositions:

  • 71 + 2147497403 = 2147497474
  • 113 + 2147497361 = 2147497474
  • 431 + 2147497043 = 2147497474
  • 503 + 2147496971 = 2147497474
  • 557 + 2147496917 = 2147497474
  • 743 + 2147496731 = 2147497474
  • 761 + 2147496713 = 2147497474
  • 821 + 2147496653 = 2147497474

Showing the first eight; more decompositions exist.
