Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147540072, here are decompositions:

  • 31 + 2147540041 = 2147540072
  • 199 + 2147539873 = 2147540072
  • 283 + 2147539789 = 2147540072
  • 499 + 2147539573 = 2147540072
  • 541 + 2147539531 = 2147540072
  • 619 + 2147539453 = 2147540072
  • 751 + 2147539321 = 2147540072
  • 883 + 2147539189 = 2147540072

Showing the first eight; more decompositions exist.
