Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147496902, here are decompositions:

  • 43 + 2147496859 = 2147496902
  • 73 + 2147496829 = 2147496902
  • 151 + 2147496751 = 2147496902
  • 571 + 2147496331 = 2147496902
  • 601 + 2147496301 = 2147496902
  • 631 + 2147496271 = 2147496902
  • 709 + 2147496193 = 2147496902
  • 1051 + 2147495851 = 2147496902

Showing the first eight; more decompositions exist.
