Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498230, here are decompositions:

  • 41 + 2147498189 = 2147498230
  • 83 + 2147498147 = 2147498230
  • 89 + 2147498141 = 2147498230
  • 113 + 2147498117 = 2147498230
  • 197 + 2147498033 = 2147498230
  • 281 + 2147497949 = 2147498230
  • 461 + 2147497769 = 2147498230
  • 569 + 2147497661 = 2147498230

Showing the first eight; more decompositions exist.
