Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488500, here are decompositions:

  • 71 + 2147488429 = 2147488500
  • 83 + 2147488417 = 2147488500
  • 89 + 2147488411 = 2147488500
  • 167 + 2147488333 = 2147488500
  • 193 + 2147488307 = 2147488500
  • 251 + 2147488249 = 2147488500
  • 337 + 2147488163 = 2147488500
  • 347 + 2147488153 = 2147488500

Showing the first eight; more decompositions exist.
