Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147540834, here are decompositions:

  • 3 + 2147540831 = 2147540834
  • 13 + 2147540821 = 2147540834
  • 67 + 2147540767 = 2147540834
  • 181 + 2147540653 = 2147540834
  • 193 + 2147540641 = 2147540834
  • 277 + 2147540557 = 2147540834
  • 367 + 2147540467 = 2147540834
  • 463 + 2147540371 = 2147540834

Showing the first eight; more decompositions exist.
