Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484870, here are decompositions:

  • 19 + 2147484851 = 2147484870
  • 79 + 2147484791 = 2147484870
  • 137 + 2147484733 = 2147484870
  • 149 + 2147484721 = 2147484870
  • 173 + 2147484697 = 2147484870
  • 191 + 2147484679 = 2147484870
  • 229 + 2147484641 = 2147484870
  • 257 + 2147484613 = 2147484870

Showing the first eight; more decompositions exist.
