Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500872, here are decompositions:

  • 59 + 2147500813 = 2147500872
  • 109 + 2147500763 = 2147500872
  • 149 + 2147500723 = 2147500872
  • 211 + 2147500661 = 2147500872
  • 281 + 2147500591 = 2147500872
  • 311 + 2147500561 = 2147500872
  • 313 + 2147500559 = 2147500872
  • 373 + 2147500499 = 2147500872

Showing the first eight; more decompositions exist.
