Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147513854, here are decompositions:

  • 137 + 2147513717 = 2147513854
  • 263 + 2147513591 = 2147513854
  • 383 + 2147513471 = 2147513854
  • 491 + 2147513363 = 2147513854
  • 677 + 2147513177 = 2147513854
  • 1013 + 2147512841 = 2147513854
  • 1031 + 2147512823 = 2147513854
  • 1187 + 2147512667 = 2147513854

Showing the first eight; more decompositions exist.
