Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147474818, here are decompositions:

  • 11 + 2147474807 = 2147474818
  • 29 + 2147474789 = 2147474818
  • 101 + 2147474717 = 2147474818
  • 107 + 2147474711 = 2147474818
  • 191 + 2147474627 = 2147474818
  • 617 + 2147474201 = 2147474818
  • 659 + 2147474159 = 2147474818
  • 809 + 2147474009 = 2147474818

Showing the first eight; more decompositions exist.
